Cooperative Incentive Model of Supply Chain Quality Control Based on Cost-sharing Contract

In order to motivate suppliers to invest more efforts to improve product quality, a game-theoretic optimization model was used to build a retailer-multi-vendor cooperative quality control incentive model based on cost-sharing contracts, and the effectiveness and rationality of the model are verified by an example. The results show that the quality control cooperation incentive model can improve the coordination effect and share the supplier’s quality control costs through retailers to promote suppliers to invest more quality efforts, increase the profits of retailers and suppliers, and thus achieve the overall profit of the supply chain maximize.

Antiretroviral therapy supply chain quality control and assurance in improving people living with HIV therapeutic outcomes in Cameroon

BackgroundEvaluation of medication efficacy and safety is an essential guarantee to successful therapeutic outcome in public health practices. However, larger distribution chain supply in developing countries such as Cameroon is often challenged by counterfeit drugs, poor manufacturing, storage and degradation leading to health and patient adverse consequences. Yet, access to supply chain management in strengthening ARVs quality assurance and outcomes remains poorly documented. More than 53,000 patients have been enrolled on free ARVs medications, but little is documented on quality assurance and validity of safety for affected populations along the supply chain management since 2008.MethodsThe cross sectional study was conducted in ARVs distribution units and centers in central, littoral and south west regions of Cameroon. ARVs drugs samples included Nevirapine, Efavirenz, and fixed dose combinations of Zidovudine + Lamivudine, Lamivudine + Stavudine and Zidovudine + Lamivudine + Nevirapine. Drugs packaging and labeling was assessed and galenic assays were performed at National Laboratory of quality Control of Medications and Expertise (LANACOME), Yaoundé, Cameroon.ResultsThe study covered 16 structures located in eight different towns including the central ARVs store, two regional pharmaceutical procurement centers and thirteen HIV approved treatment centers and management units. A total of 35 ARVs products were collected. Only eight ARVs drugs containing Lamivudine and Stavudine presented with white stains on tablets, however these drugs were standard for all other tests performed. The others 28 ARVs products were standards to all assays performed.ConclusionWe concluded that ARVs drugs freely accessible and distributed to PLWHA are of good quality in Cameroon. However, with the increase number of patients under HAART since 2013, adoption of “Test and Treat” approach to reach the 90-90-90 goals and with the implementation of new national antiretroviral regimen guidelines and molecules such as boosted protease inhibitors, continuous quality control and assurance surveillance, monitoring and evaluation is recommended. Assessment of quality of formulations that are more susceptible to degradation such as pediatric formulations for averting the rising multidrug resistance trend is also desired.

Study on Quality Prediction Technology of Manufacturing Supply Chain

Supply chain quality is the assurance of product quality in its full life-cycle. Although supply chain quality control is a hot topic among researchers, supply chain quality prediction is actually an important but unsolved problem in manufacturing industry. In this paper, an approach of manufacturing supply chain quality prediction based on quality satisfaction degree is proposed to control supply chain better, in order to help ensure product quality. Supply chain quality prediction 3D model and model based on customer satisfaction and process control are established firstly. And then technologies used in quality prediction are studied, including quality prediction index system established on Expert scoring -AHP and prediction workflow built on ABPM. Finally an example is given to illustrate this approach. The customer satisfaction prediction result of supply chain quality can help supply chain management, and the quality prediction software system can make it easier, which provides a new direction for the product quality control technology research.

Research on the FMCG Supply Chain Quality Control Tower System and Operation Mechanism

The article used collaborative control theory, Internet of Things technology and the house of quality, and then proposed an innovative concept of FMCG supply chain quality control tower based on FMCG supply chain quality features. It elaborated its operation mechanism of the "five layers and three mechanisms" that provided theoretical support for quality control and traceability of FMCG.

Supply chain and Management System based Standardization of Botanicals

In recent years with ever-growing commercialization in the field of herbal medicines, inadvertent contamination, substitution and intentional adulteration with pharmaceutical drugs in herbal plants and products are common practices. The challenges are innumerable and enormous, making the global herbal market potentially unsafe. Generally, quality control and quality assurance activities cover the entire supply chain and include good practices throughout the supply chain from cultivation to the point of use by the consumer. In practice, good manufacturing practices are used to address safety requirement of medicinal plants and herbal medicines primarily during the processing of harvested medicinal plants for conversion into products intended for consumer use. This talk seeks to enlighten physicians, pharmacists, consumers, manufacturers and stake holders in herbal medicine of the need to establish quality parameters for cultivation, collection, handling, processing and production of herbal medicines as well as employ such parameters in ensuring the safety of the global herbal market. The processes of good quality assurance and standardization of herbal medicines and products will also be discussed in detail with regard to WHO guidelines. This presentation will cover current perspectives for addressing all aspects for supply chain quality control and assurance of botanicals from cultivation to consumer use, an attempt has been made for a sequential study of the quality control of herbal medicinal products (HMP) starting from selection of medicinal plants; good agricultural practices (GAP); cultivation; good field collection practices (GFCP); organized and unorganized drugs; source and period of collection; identification; storage chemical standardization; assay; good manufacturing practices (GMP); pharmacological study to clinical approach, with special reference to maintain standardization at each and every stage. Modern techniques used for quality, safety and quality control will be discussed in detail to outline the challenges of standardization with special reference to marker compounds in plant species and their fingerprinting. Practical experiences of laboratory work on inadvertent contamination and substitution as well as intentional adulteration with pharmaceutical drugs in herbal plants and products will been discussed in detail.
