In addition, RFID also controls the material distribution designation and year of procurement. So that the distribution of material as hospital assets will be recorded accurately and the health services provided can also run well and have good quality.

The Supply Chain Management Mechanism for Materials Procurement in The Construction Industry

Supply chain management is now widely used in business, especially in the manufacturing sector. The same principles being applied to the construction industry demonstrates how pervasive and persistent issues are. Since building materials are essential to the construction industry and are used in all types of projects, regardless of the client's original concept, the significance of this study is on the manufacturing of building materials. Although supply chain management appears to be a complicated system comprising numerous vendors, contractors, and subcontractors, it holds great promise for achieving the successful integration of different disciplines and stakeholders. The supply chain management for building materials is being examined using a quantitative methodology. The capability of procurement to allocate resources in a way that supports organizational dynamics and policy. As a result, the greatest mean value (4.37), which represents the range of the variables, best captures the individuality of construction projects (the construction of each project is different in size, resources, and implementation on method). The respondents all agreed that the range of factors influencing supply chain management, which has the highest mean of these features, is what makes construction projects unique. An inadequate organizational structure came in third with a mean of 4.30, trailing only the absence of an acceptable information technology system, which came in second with a mean of 4.36. As a result, supply chain management and procurement is a hotly debated subject for raising performance and quality. Several companies or organizations need the computer-based system to test the most recent supply chain management techniques as part of future research. A technique for the effective and efficient control and monitoring of the purchasing function is procurement that buys performance.

Polynesian quarrying at the bottom of the world – Raw material procurement and adze production in Bluff Harbour, South Island, New Zealand

Bluff Harbour, Murihiku (Southland) was the location of a stone tool production system during the earliest period of New Zealand settlement by Polynesians. The system focused on the production of adzes from Bluff argillite, a tough metasedimentary rock obtained primarily from Coylers Island in the north of the harbour. To better understand quarrying and reduction strategies on Colyers Island, we undertook investigations there which included the surface collection of 148 adze blanks and test excavations. We created 3D models of these blanks to analyse raw material properties and reduction strategies. The results established there was a single manufacturing sequence that began at the Colyers Island quarry and finished at the nearby settlement site of Tiwai Point, as the same blank selection strategies and manufacturing techniques were observed at both locations. Importantly, a marked distinction was made between the early-stage blanks from Colyers Island, and the later stages of reduction of Tiwai Point blanks and preforms. The connection between these two locales indicates a distinct system of adze manufacture that was established to supply adzes to communities up to 500 km distant.

A time series analysis approach to forecast price fluctuation points

ABSTRACT For manufacturers, material procurement and product sales directly influence cash flows. Buying materials at lower prices and selling products at higher prices is the easiest way to increase revenue. If a company can predict the price fluctuations in materials or products accurately, then it can maximize its profit by taking the appropriate action at the right time. This study proposes a novel price fluctuation forecast model, that is, the price fluctuation point forecast approach (PFPFA), to anticipate price fluctuation points and the degrees of price changes. Price fluctuation data are non-uniform time series. Hence, this study focuses on the quantities that predict price fluctuation points rather than the price fluctuation time epoch. The PFPFA encompasses four models to predict the price fluctuation points and three models to predict the price differences between periods. Thus, for each product, 12 forecast outcomes are possible. Applied to a real-world scenario and compared with exponential smoothing, the PFPFA offers acceptable predictions about price fluctuation points and performs better with regard to the degrees of price changes.

The Joint Decision-Making Support through Piecewise Objective Optimization Model for Integrated Supplier Selection, Inventory Management, and Production Planning Involving Discounts

The decision-makers in manufacturing industries continuously optimize every supply-chain part to achieve optimal profit. In this paper, three crucial activities in the supply chain are observed as profit contributors: supplier selection, inventory management, and production planning. Decision-making support is needed to optimize those activities, especially when prices/costs involve discounts. Therefore, this study aims to develop integrated decision-making support for supplier selection, inventory management, and production planning involving discounted prices. The problem was considered with multi-supplier, multi-raw material, multi-product, and multi-observation time instant. The objective was based on maximizing the profit for the entire activity, i.e., from the raw material procurement and storage to the production. This supply chain was modeled as mixed-integer linear programming with a piecewise objective function representing the profit, which was maximized. It was also modeled with a bunch of constraint functions, including product demand satisfaction. The proposed model was tested with computational simulations using randomly generated supply chain data. The primal simplex algorithm was also employed to calculate the real value of the optimal decision, which was combined with the Branch-and-Bound approach to calculate the appropriate integer solution. The results showed that the optimal decision was achieved, namely (1) The optimal quantity of raw materials ordered to each supplier, (2) The optimal production quantity, and (3) The optimal inventory level, which provided the maximal profit for the whole optimization time horizon. This indicated that the proposed decision-making support model is implementable for industrial decision-makers.

Prioritising materials procurement and construction waste management attributes

Construction and demolition waste constitutes the largest municipal solid waste globally with environmental concerns. However, waste management is not considered a priority objective in construction compared to time and cost. Therefore, construction practitioners’ waste management priority is evaluated in this study. A review of the literature revealed waste management attributes from multiple perspectives. A questionnaire survey was adopted to solicit practitioners’ contributions on their importance. Then, the attributes were prioritised and categorised into high, medium and low priorities using the voting analytical hierarchy process. Empirical results indicate that the high-priority materials procurement attributes were alliance with suppliers, a take-back clause in the suppliers’ agreement document, accurate material quantification, accurate material ordering and a just-in-time delivery plan. Senior managers’ early commitment to waste minimisation, effective communication among project participants, making subcontractors responsible for their waste, identifying recyclable materials and identifying reusable materials were high-priority attributes for managing waste in the construction stage. The findings of this study indicate areas where contractors should focus effort to improve waste management in the industry by collaborating with subcontractors and suppliers. Future studies should focus on developing frameworks that provide actionable means for implementing waste management attributes identified in this research study.

DESIGNING A COLLABORATIVE MODEL FOR THE RAW MATERIAL PROCUREMENT PROCESS TO ELEVATE THE FURNITURE INDUSTRY COMPETITIVENESS

The furniture industry is a non-oil and gas sector that can be developed aggressively due to the abundant natural resources provided by Indonesia's forests. However, there are several issues in the wooden furniture industry, starting on the upstream supply chain, especially in the raw material procurement process. The increasing product cost because of high procurement costs could make this industry hard to compete or grow. Thus, this study proposes an improvement of raw material procurement by developing a collaborative model to minimize the total circular procurement cost in the wooden furniture industry supply chain. Adopting the collaborative model is expected to reduce the raw material procurement costs of all parties involved in the supply chain by shortening the supply chain. In addition, this study built a dynamic system model with an implementation circular supply chain concept, which focuses on regenerating the wood raw material toward zero waste. The finding is that a collaborative model could reduce the total circular procurement cost by 25% to 35% compared to the base model. A recommendation for building the terminal comes from the collaborative model. The result of this study provides a solution to elevate the furniture industry's competitiveness through cost reduction.

Optimization and research of the nonlinear programming model of the full cost of pre-ironmaking under carbon emission reduction constraint

Under the overall requirements of China’s implementation of the “Dual Carbon” strategy and green manufacturing, the iron and steel industry will face severe challenges from carbon emission reduction in addition to costs. Pellet’s substitution of sintering is an important measure to effectively reduce the waste gas pollution load of pre-ironmaking, reduce energy consumption and carbon emission reduction, and is an important way for iron and steel industry to move towards green manufacturing. The cost reduction proposed in this paper is not limited to considering the intermediate processes such as procurement, sintering and pelletizing, but the overall consideration of the whole process from raw material procurement to blast furnace production. With the maximum molten iron profit as the objective function, the key factors such as ore inventory, sinter, pellets, molten iron and slag are comprehensively considered, and the mechanism model is established according to the comprehensive consideration of material flow, energy flow and information flow. Through the support of the system, it not only improves the pig iron profit, improves the metallurgical performance of the burden structure and slag performance, and promotes the smooth running of the blast furnace, but also reduces the market risk caused by the concentrate and lump ore inventory in the current period.

Research on construction schedule risk management of power supply and distribution projects based on MCS-AHP model

In order to manage the construction schedule risk of power supply and distribution engineering, a construction schedule risk evaluation model, namely the Monte Carlo simulation method - Analytic Hierarchy Process (MCS-AHP) model, is proposed. In this model, the Monte Carlo simulation method is adopted to improve the analytic Hierarchy Process (AHP), and the normal distribution interval is used to replace the specific value when constructing the fuzzy complementary judgment matrix, to reduce the risk of fuzzy thinking and incomplete information or scattered data in the process of investigation and judgment and improve the scientific evaluation. This paper takes a power supply and distribution project in Guangdong Province as an example uses the MCS-AHP model to measure the key factors limiting the project progress, and uses the AHP method for comparative analysis, to verify the feasibility of the MCS-AHP model. The analysis shows that the key influencing factors are material and equipment procurement, production and arrival, installation of 10 kv high voltage switchboard, electrical acceptance and single machine commissioning, installation of low-voltage switchboard and DC switchboard, and foundation construction of power station equipment, etc., which are consistent with the actual situation. Therefore, it is feasible to construct the MCS-AHP model, which can provide a new way of thinking for schedule risk management analysis.
