Measuring Cost of Quality (COQ) seems to be a critical factor for organizations in order to keep or grow their market share. However, until now the COQ has been measured almost exclusively only internally, i.e. within a company, while the role of a supply chain in delivering quality product to end users has been ignored. In this paper we argue that all the entities within supply chain affect the quality of a product or a service and their quality related activities should thus be inevitably considered. The objective of this research is to develop a mathematical model to estimate COQ as key performance measurement within manufacturing supply chain while considering quality Excellency status. Using classic PAF (Prevention-Appraisal-Failure) model classification to develop mathematical model and its integration with significant variables in supply chain entities are the key methodology in this work. Perceived quality is assumed as an appropriate definition of quality in manufacturing supply chain. Moreover, proposed model is examined against real time quality cost data of manufacturing supply chain in two intervals, first at quality immaturity period and then at quality maturity period. Statistical tools are used to validate the model and compare its behaviour in the two intervals. The results are then analyzed and discussed, and possible future works are presented.

Blending technologies play an important role in manufacturing. The design and operation of manufacturing processes using blending technologies represent a special range of manufacturing related logistics because the integrated approach of technological and logistic parameters is very significant. This research proposes an integrated model of supply of manufacturing processes using blending technologies. After a careful literature review, this paper introduces a mathematical model to formulate the problem of supply chain design for blending technologies. The integrated model includes the optimal purchasing strategy depending on the characteristics of components to be mixed in the desired proportion and the costs of supply. The integrated model will be described as a linear programming problem. Numerical results with different datasets demonstrate how the proposed model takes technological and logistic aspects into consideration.

Halal Food

As the demand for halal food becomes raising and the supply of halal food is limited, it is required a strategy to optimize the halal food supply chain. The optimization of halal food supply chain can support its sustainability. Therefore, study about halal food supply chain optimization is required. This paper try to develop a mathematical model, entitled as Balance Halal Supply Chain (BHSC) model. This model propose a distribution strategy for halal food supply chain from limited halal slaughterhouses to several halal markets so as the total cost of distribution becomes minimize. It is assumed that all halal market demands must be fulfilled, so the lack ness cost becomes zero. The model try to fulfill all the halal market demands and minimize the oversupply and transportation costs. BHSC is modeled as MILP. Numerical experiment is performed to validate the model and it is solved by CPLEX Solver Version 12.6.3. Based on the experiment result, it is shown that the model can be used by halal supply chain decision maker as the decision making tool to design the best strategy for distributing the limited number of halal meat to many halal markets for its supply chain sustainability. The BHSC model can minimize the total cost of distribution that consists of oversupply and transportation costs, in the case of all halal market demands must be fulfilled. In conclusion, the proposed model becomes an alternative method to support the halal food supply chain sustainability.

AbstractOver the last decades, circular economy and its implications for sustainability have gained momentum in several socio-economic domains (e.g., academia, industry, politics, society), even though the relationship between them remains poorly understood. This situation has blurred the conceptual definition of both terms, limiting their research and practice effectiveness. To counteract this situation, scholars and policymakers are approaching Circular Economy as able to inspire the development of sustainable development strategies and to increase the sustainability of the current economic system, balancing the need for economic development and the importance of protecting environmental resources and people wellbeing. Drawing on the previous considerations, this study aims to contribute to address this gap, better understanding how a circular economy approach can contribute to challenge the number of sustainability issues that currently affect supply chains. In doing so, the analysis has been focused on the investigation of a specific supply chain, the pasta supply chain. To this end, after a brief theoretical recognition, an interpretative model has been proposed for better recognizing and describing the enhancing actions that—at each supply chain’s stages—can improve process efficiency, output effectiveness and, therefore, the overall sector sustainability. However, it is worth noting that the inherently theoretical nature of the study somewhat limits it; therefore, future empirical research is needed to further test the proposed model, applying it to other real applicative sets.

The Mathematical Model

The paper presents the system of predicting the indicators of accreditation of technical universities based on J. Forrester mechanism of system dynamics. According to analysis of cause-and-effect relationships between selected variables of the system (indicators of accreditation of the university) there was built the oriented graph. The complex of mathematical models developed to control the quality of training engineers in Russian higher educational institutions is based on this graph. The article presents an algorithm for constructing a model using one of the simulated variables as an example. The model is a system of non-linear differential equations, the modelling characteristics of the educational process being determined according to the solution of this system. The proposed algorithm for calculating these indicators is based on the system dynamics model and the regression model. The mathematical model is constructed on the basis of the model of system dynamics, which is further tested for compliance with real data using the regression model. The regression model is built on the available statistical data accumulated during the period of the university's work. The proposed approach is aimed at solving complex problems of managing the educational process in universities. The structure of the proposed model repeats the structure of cause-effect relationships in the system, and also provides the person responsible for managing quality control with the ability to quickly and adequately assess the performance of the system.

Football Industry

PurposeTo understand the football industry in its entirety, a supply chain management (SCM) approach is necessary. This includes the study of suppliers, consumers and their collaborations. The purpose of this study was to present a business management model based on supply chain management.Design/methodology/approachData were collected through in-depth interviews with 12 academic and executive football experts. After three steps of open, axial and selective coding based on grounded theory with a paradigmatic approach, the data were analysed, and a football supply chain management (FSCM) was developed. The proposed model includes three managerial components: upstream suppliers, the manufacturing firm, and downstream customers.FindingsThe football industry sector has three parts: upstream suppliers, manufacturing firm/football clubs and downstream customers. We proposed seven parts for the managerial processes of football supply chain management: event/match management, club management, resource and infrastructure management, customer relationship management, supplier relationship management, cash flow management and knowledge and information flow management. This model can be used for configuration, coordination and redesign of business operations as well as the development of models for evaluation of the football supply chain's performance.Originality/valueThe proposed model of a football supply chain management, with the existing literature and theoretical review, created a synergistic outcome. This synergy is presented in the linkage of the players in this chain and interactions between them. This view can improve the management of industry productivity and improve the products quality.

Semantic Mediation

Healthcare systems have evolved to become more patient-centric. Many efforts have been made to transform paper-based patient data to automated medical information by developing electronic healthcare records (EHRs). Several international EHRs standards have been enabling healthcare interoperability and communication among a wide variety of medical centres. It is a dual-model methodology which comprises a reference information model and an archetype model. The archetype is responsible for the definition of clinical concepts which has limitations in terms of supporting complex reasoning and knowledge discovery requirements. The objective of this article is to propose a semantic-mediation architecture to support semantic interoperability among healthcare organizations. It provides an intermediate semantic layer to exploit clinical information based on richer ontological representations to create a “model of meaning” for enabling semantic mediation. The proposed model also provides secure mechanisms to allow interoperable sharing of patient data between healthcare organizations.

Proposed Model

Laboratory scale experiments were conducted to develop a mathematical model for the anaerobic digestion of a mixture of night soil and septic tank sludge. The optimum mixing ratio by volume between night soil and septic tank sludge was found to be 7:3. Due to the high solids content in the influent waste, mixed-liquor volatile suspended solids (MLVSS) was not considered to be a proper parameter for biomass concentration, therefore, the active biomass concentration was estimated based on deoxyribonucleic acid (DNA) concentration in the reactor. The weight ratio between acidogenic bacteria and methanogenic bacteria in the mixed culture of a well-operated anaerobic digester was approximately 3:2. The proposed model indicates that the amount of volatile acid produced and the gas production rate can be expressed as a function of hydraulic residence time (HRT). The kinetic constants of the two phases of the anaerobic digestion process were determined, and a computer was used to simulate results using the proposed model for the various operating parameters, such as BOD5 and volatile acid concentrations in effluent, biomass concentrations and gas production rates. These were consistent with the experimental data.
