Benefits and Barriers of Digital Procurement: Lessons from an Airport Company

Implementing a well-integrated procurement system and applying uniform practices to achieve the strategic goals of any company is a complex phenomenon. Navigating the digital procurement systems in achieving supply-chain resilience remains a predicament. Framed within the technology acceptance model (TAM), which is a key model in understanding the predictors of human behaviour toward the potential acceptance or rejection of the technology. This study explored the benefits and barriers of digital procurement at Airports Company South Africa (ACSA). A qualitative approach in a form of a single holistic case study design was adopted. The sample involved 18 employees and individuals who were supply chain management (SCM), information technology (IT), and programme management office (PMO) professionals. Semi-structured interviews conducted focused on those with extensive experience on procurement, digital technologies, procurement automation or the implementation of transformation programmes. Digital procurement is a value-adding function at ACSA with the possibilities of providing cost reduction in the supply chain. However, the participants highlighted job losses, cyber security, lack of interoperability, lack of skills and system downtimes as obstacles affecting the adoption of digital procurement and as organizational barriers. The infusion of digital technologies into various aspects of organisational processes and outcomes remains a complex, dynamic, fluid, and volatile phenomenon. A framework highlighting critical focus areas when it comes to the adoption of digital procurement of digitalization is presented.

Understanding demand and supply side factors: a cross-sector analysis from Saudi Arabia

PurposeIntegrating demand with supply has always been an evolving research area, which is affected by different factors including, but not limited to, sustainability, changing consumer demands and emerging supply chain practices. However, most of the research targeted developed countries due to better data access and enhanced information visibility. The research on supply and demand integration in Saudi Arabia is still in its infancy. This study explores this gap by providing a comprehensive analysis of demand and supply chain integration in the context of sustainability. This is done by first creating a developing countries-based research framework and then validating it through surveying 162 Saudi companies operating in multiple sectors like food, fashion and retail. Results suggest that there is more emphasis on supply-side factors relative to demand-side factors in the context of integration. Demand side factors only marginally impact waste reduction efforts. Similarly, the food sector is most sensitive to integration efforts attaching high importance to sustainability and efficiency initiatives. These results can be a useful guide for managers and policymakers who are planning and executing at the interface of demand and supply chains in developing countries.Design/methodology/approachCross-sector analysis by survey questionnaire of 162. Descriptive statistical analyses were performed on the data for the study participants. Continuous variables were summarised using mean and standard deviation (SD), median and IQR; and proportions were used for nominal and ordinal variables. A total score measuring perception of employees towards supply–demand integration was analysed and compared by company-related factors (sector/industry, length of service in firm (years) and the number of employees). Comparisons were made using the chi-square test or ANOVA. A linear regression model was utilised to examine the independent effect of supply and demand side factors on employees' perception of integration. The model controlled for the sector, length of service and number of employees. Statistical significance was considered at p < 0.05.FindingsThe linear regression results showed that supply items significantly predicted integration. That is, higher supply–demand integration scores were significantly related to indicators for using supply variables in supply chain management (SCM) improves operational efficiency (OE), integrating supply variables at the execution stage reduces overall waste and including at least one supply-side variable in supply planning (p < 0.05). The indicator for integrating demand variables at the execution stage reduces overall waste was only marginally related to an increased integration scores (p = 0.089). Lastly, a significantly better perception of supply–demand integration was reported by employees in the food sector compared to those in the fashion sector (p = 0.018). Length of service or number of employees in the firm was not related to perception towards supply–demand integration.Research limitations/implicationsThough accessing 162 companies in the Saudi market is a significant sample size given the fact that they are quite conservative in sharing supply and demand information. However, for better generalisation and richer insights, more sectors like manufacturing, oil and gas and hospitality should be added in future. Cross-country analysis from developing countries can be another interesting future direction.Originality/valueThis empirical paper draws its strength from the scale and depth of empirical data collected from Saudi companies belonging to multiple sectors to better understand demand and supply chain integration, especially from sustainability and waste reduction. This is true in the era of the pandemic and its associated risks for both upstream and downstream. The developing countries' perspective is important as not enough is written in the literature given the difficulties in accessing the information and subsequent analysis. The insights are bound to be unique as a consumer in these countries is undergoing significant socioeconomic changes affecting the supply chain of the companies.

The Correlation between Supply Chain Performance and Information Technology

Supply Chain Performance is regarded as a crucial organizational performance indicators. Much effort has been made to enhance it. So, effective and efficient supply chains are recognized as a crucial strategic aspect for achieving several essential corporate objectives, such as improved customer service, enhanced efficiency, and enhanced competitiveness. Therefore, the objective of this study is to analyze the role of information technology on supply chain performance with information technology support as a mediator. The study has been designed based on a descriptive approach using a survey to collect data by questionnaire from Saudi logistics professionals. The potential respondents were members of Hyper Panda's top level of management and executive personnel who were familiar with the company's operations and supply chain procedures. There are 83 valid responses. The research result has several findings and outcomes that will inform future research. The study findings will shed light on choosing the most effective information technology with a significant influence on supply chain performance.

Three-layer business model canvas (TLBMC) as a recycling support tool to achieve sustainable development goals in waste management systems.

Traditional strategies for waste management in developing countries face high-cost problems, severe pollution, limited viable data, lack of global coverage, inefficiency, and slowness. The rapid expansion of the Internet have made new opportunities in waste management, especially waste collection. Online waste management in developing countries can create a revolution and help the government and society to achieve the goals of sustainable development. In this study, a modified three-layer business model canvas (TLBMC) was used to describe the duties of each actors involved in waste management and interactions between different elements in order to show the existing capacities in view point of economic, social, and environmental dimensions. In this online marketplace, the flow of information, the flow of materials and the flow of money in any company or entity or person active in the field of waste, are effectively connected to each other. Supply and demand information is provided in the created platform, and various waste actors are connected to look for options to trade. After agreement between the customer and the buyer, the information is delivered from the website or platform created by the supplier to the applicant. This network can have its usual structural features and create appropriate mechanisms for the continuation of its business operation and the realization of sustainable development of waste management, especially the recycling industry.

Influence Mechanism of Construction Supply Chain Information Collaboration Based on Structural Equation Model

The construction supply chain has many stakeholders and complex and diverse information, which cause various information exchange problems that diminish project management efficiency. Thus, information collaboration is an important factor in the construction supply chain. This study aims to improve the efficiency of project management by analyzing the factors hindering information collaboration in the construction supply chain in order to determine their internal influencing mechanisms. The relevant data of 281 construction employees is collected by questionnaire survey. The relationship among stakeholders (SH), information technology (IT), external stability mechanism (ESM), and information collaboration is then quantitatively evaluated based on the structural equation model (SEM). The results show that stakeholders, information technology, and the external stability mechanism have an influence on information collaboration, while stakeholders do not have a significant influence. Information technology and the external stability mechanism significantly influence information collaboration and provide a mediation role between stakeholders and information collaboration. The innovation of this work is the quantification of information collaboration influencing factors in the construction supply chain and the analysis of its potential path relationship according to the mediating effect test. Its theoretical contribution is to address the research gap in construction supply chain information collaboration and expand the research scope of construction project collaborative management regarding information collaboration. Finally, this work has a practical contribution by providing suggestions for improving the efficiency of building supply information collaboration.

Smart Sales Empower Small Farmers: An Integrated Matching Method between Suppliers and Consumers Based on the Information Axiom

Small farmers’ sustainable development has important significance for narrowing the gap between urban and rural areas and hastening the promotion of general prosperity in China. Currently, China still has 240 million small farmers. The sale of agricultural products is an important source of their income. Constrained by their small scale, lack of capital, and technology, small farmers often have to adopt a household operation mode. This decentralized agricultural production and operation mode results in significant difficulties for small farmers to benefit from planting and selling agricultural products. Many efforts have been made to help them, such as establishing agricultural product information platforms that can provide supply and demand information to facilitate small farmers’ sales. However, imbalances between suppliers and consumers and cross-regional transaction difficulties still exist. To promote the sustainable development of small farmers, this study develops an intelligent matching method for the transaction of agricultural products between suppliers and consumers. Firstly, a unique attribute set for agricultural products was established. Because most agricultural products are fresh, perishable, and not easily preserved, the general attributes (brand, logistics distance, product grade, and price) of commodities and the specific attributes (freshness, maturity, product certification, seasonal products, place of origin, and product safety) of agricultural products were taken into account. Secondly, by combining fuzzy mathematics with the information axiom, improved amount of information calculation methods for both quantitative and qualitative attributes were put forward. Thirdly, based on the amount of information about all attributes and with the goal of maximizing the transaction-matching degree for both the supplier and consumer, a multiobjective optimization model was proposed. Finally, the effectiveness and accuracy of the method were verified through a case study. In order to solve the dilemma of small farmers, this study proposes an integrated matching method for agricultural product transactions based on the information axiom. Through case verification, this method has good feasibility and effectiveness. It has broad application prospects which can be applied to information portals, e-commerce platforms, and other fields. The application of this method can empower small farmers’ capabilities, facilitate agricultural product sales, and promote small farmers’ sustainable development.

With Huawei as the primary research object, this paper explores the basic methods of digital and intelligent supply chain transformation from the six aspects of production planning, digital sales, building logistics parks, process learning, order signing, and supply chain collaboration, clarifies the advantages of digital and intelligent supply chain data analysis and information transmission, and expects to form a systematic method that can be referenced.

Sustainable Management of Food Waste during COVID-19 Pandemic: Insights into Irrational Food Hoarding among Chinese Citizens.

During the COVID-19 pandemic, food waste caused by excessive hoarding has accounted a large proportion of the total food waste in urban Chinese households, which indicates that reducing food hoarding has become key to managing household food waste. This study therefore explored the behavioral mechanisms underlying excessive food hoarding among citizens. Based on a sample set of 511 respondents surveyed in Beijing, Hefei, and Guiyang in July 2022, a PLS-SEM model was conducted using SmartPLS 3.0 software to simulate the decision-making process of food hoarding. The following results were found. First, among the households with hoarding, 66.37% had some degree of food waste. Second, hoarding preference was the direct predictor of hoarding behavior, which means that hoarding behavior can be effectively controlled by regulating preferences. Third, group influence including homology consistency and social network support, as well as psychological panic, both enhanced citizens' hoarding preference and induced hoarding behavior. Therefore, it is necessary to weaken group influence and try to help citizens overcome panic. Finally, food supply information release can not only alleviate citizens' psychological panic and weaken group influence, but also block the transformation of preference into behavior. The above results are of great importance for the design of management policies for food waste caused by irrational hoarding during the pandemic.

A BIM–WMS Management Tool for the Reverse Logistics Supply Chain of Demolition Waste

In the construction industry, the reverse logistics supply chain (RLSC) is one of the measures used to effectively manage demolition waste. However, there are still many problems associated with its operation, including inaccurate calculation of demolition waste supplies and insufficient interaction between supply and demand information, and waste suppliers usually choose transportation alternatives associated with high carbon emissions to obtain economic benefits. These issues have hindered the sustainable development of the RLSC. This paper proposes a waste recycling facility selection system (WRFSS) that integrates building information modeling (BIM), web map service (WMS), and an application programming interface (API) plug-in. Compared to the actual transportation scenario, the transportation distance of the WRFSS was reduced by 30.6 km and the amount of carbon dioxide emissions were reduced by 0.0259 tons. This selection system realizes an optimal selection mechanism for waste recycling facilities and develops the shortest transportation plan, thereby reducing carbon emissions during transportation and achieving sustainable development.

PERANCANGAN SISTEM INFORMASI PERSEDIAAN OBAT BERBASIS WEB PADA APOTEK BANTARJAYA BEKASI

Based on the results of researchers' observations of the Bantarjaya Pharmacy, especially the drug procurement system, this research was carried out. The drug procurement process at the Bantarjaya Pharmacy is currently out of control and faces various challenges. Among them, there are often inconsistencies between recorded drug data and drugs that are actually available, and reports are still made manually, so that data recording becomes incorrect and ineffective. Expired but not easily identifiable drugs is another problem that often arises. The researcher came to the conclusion that the Bantarjaya Pharmacy needed a good drug supply system to make it easier for officers to collect drug data, both incoming and outgoing, as well as for stock verification. The waterfall method, data collection techniques, observations, interviews, and literature studies are used in the design of this drug supply information system. The design of a computerized drug supply information system can be an ideal way to overcome the problems that exist at the Bantarjaya Pharmacy which used to still use a manual approach. Because Bantarjaya Pharmacy can operate more effectively and efficiently if there is a computerized system.

Tidal Effect on Grouting in Karst Fracture with Flowing Water: Experimental Investigation and Its Application

To address the problem on grouting control of water inflow disaster in coastal area, a caisson-type grouting experimental system of a single fracture in flowing water under tidal action was developed independently. Through the tide simulation system, the tidal action of different intensity and frequency was effectively described. Tide simulation system, fracture system, grouting system, water supply system and information monitoring system were combined to realize the visualization of the whole grouting process under tidal action. Furthermore, the grouting experiments of a plate fracture under different tidal action were developed and the blocking mechanism under tidal action was revealed. The conclusions were as follow: 1) Under constant water head, the slurry had three typical diffusion patterns, which were circular distribution, double U-shaped distribution and elliptical distribution respectively. 2) Under tidal action, the pressure showed a periodic fluctuation growth, and the growth rate slowed down with the increase of fracture aperture. 3) Strong tidal action would promote the diffusion of and increased the outflow amount of slurry, which was not conducive to grouting. Based on the water inflow treatment project of limestone mine in Guangxi, Through the field grouting tests, the 2# water inflow point was blocked. The research results have a certain reference value for the technology optimization of grouting engineering in coastal areas.

A data-informed approach using individualised dispensing patterns to estimate medicine exposure periods and dose from pharmaceutical claims data.

Pharmaceutical claims data are often used as the primary information source to define medicine exposure periods in pharmacoepidemiological studies. However, often critical information on directions for use and the intended duration of medicine supply are not available. In the absence of this information, alternative approaches are needed to support the assignment of exposure periods. This study summarises the key methods commonly used to estimate medicine exposure periods and dose from pharmaceutical claims data; and describes a method using individualised dispensing patterns to define time-dependent estimates of medicine exposure and dose. This method extends on important features of existing methods and also accounts for recent changes in an individual's medicine use. Specifically, this method constructs medicine exposure periods and estimates the dose used by considering characteristics from an individual's prior dispensings, accounting for the time between prior dispensings and the amount supplied at prior dispensings. Guidance on the practical applications of this method is also provided. Although developed primarily for application to databases, which do not contain duration of supply or dose information, use of this method may also facilitate investigations when such information is available and there is a need to consider individualised and/or changing dosing regimens. By shifting the reliance on prescribed duration and dose to determine exposure and dose estimates, individualised dispensing information is used to estimate patterns of exposure and dose for an individual. Reflecting real-world individualised use of medicines with complex and variable dosing regimens, this method offers a pragmatic approach that can be applied to all medicine classes.

ABSTRAC Blood donation is the process of voluntarily giving blood for the purpose and purpose of blood transfusion for other people in need. The process of delivering information related to blood stock, the public must always visit PMI, so it is inefficient and less effective. Many want to stock up blood to help others, but because of the lack of information, people don't know how to find out the location of existing blood stocks. The result of this research is a blood stock application that is able to provide blood bag stock data, as well as blood stock information. This makes it easier for users to find information about the method, place, and requirements for blood stock so that it is hoped that the public (users) who need blood supply information can access accurate and reliable information that has been presented by the PMI or UTD concerned.

Multiple mechanisms contribute to fluorometry signals from the voltage-gated proton channel

Voltage-clamp fluorometry (VCF) supplies information about the conformational changes of voltage-gated proteins. Changes in the fluorescence intensity of the dye attached to a part of the protein that undergoes a conformational rearrangement upon the alteration of the membrane potential by electrodes constitute the signal. The VCF signal is generated by quenching and dequenching of the fluorescence as the dye traverses various local environments. Here we studied the VCF signal generation, using the Hv1 voltage-gated proton channel as a tool, which shares a similar voltage-sensor structure with voltage-gated ion channels but lacks an ion-conducting pore. Using mutagenesis and lipids added to the extracellular solution we found that the signal is generated by the combined effects of lipids during movement of the dye relative to the plane of the membrane and by quenching amino acids. Our 3-state model recapitulates the VCF signals of the various mutants and is compatible with the accepted model of two major voltage-sensor movements.

First isolation of a trh positive V. alginolyticus from Atlantic bluefin tuna (Thunnus thynnus) farmed in Turkey

Popularity of sushi-sashimi (raw-almost raw fish service) is increasing around the globe, and Atlantic bluefin tuna is among the most frequently used fish in these dishes. In this study, trh (Thermostable direct hemolysin-related hemolysin gene) positive Vibrio alginolyticus was isolated from the internal organs of two tuna sent to the laboratory from a farm in Aegean region of Turkey in 2014. Isolation was done by conventional microbiological methods and Vitek 2 Compact fully automatic identification device was used for identification. Isolate confirmation and investigation of trh-tdh (Thermostable direct hemolysin) gene existence were carried out by a Polymerase Chain Reaction (PCR) method. Two V.alginolyticus isolates from two tuna were found to be trh positive and tdh negative. trh is one of the important genes associated with pathogenicity in the Vibrio genus, and raw consumption of tuna infected with trh positive V.alginolyticus can cause serious food poisoning. The aim of this study is to report first isolation of trh positive Vibrio alginolyticus from two bluefin tuna cultured in the Aegean sea, to draw attention to possible dangers in raw-almost raw fish consumption and supply information for further epidemiological studies. However, more samples are necesary for mentioning the prevalence of high virulence food pathogens in tuna. However, due to their economic value, multiple tuna samples are rarely sent to laboratories for diagnostic purposes.
