There exist several ways to model supply chain systems, from discrete models to stochastic ones. Among them there is a modeling approach based on traffic flow theory which considers inventory levels and material flows. The resulting models are linear, although they are subject to constraints such as maximum production rates, as well as non negative inventory values and material flows. These constraints...
Plant location decision is important in supply chain design and optimization. Traditional evaluation of KPIs affecting one plant includes quality's and cost's aspects. Now the competitions between companies have changed to the competition between supply chains. This paper presents a new KPI evaluation system for plant relocation from the viewpoint of the entire supply chain optimization by considering...
Model Predictive Control (MPC) offers an attractive way to systematically address uncertainty in demand forecasts, factory execution, or external supply and effectively mitigate potential under-damped responses in the closed-loop system. However, other practical concerns may preclude the use of classical formulations of MPC. Of particular importance is the ability to ship material through auxiliary...
There are several published solid state lighting roadmaps which typically focus on materials and device research. The iNEMI (International Electronics Manufacturing Initiative) Solid State Illumination (SSI) Roadmap complements these roadmaps with a supply chain focus and an industry needs assessment that is broader than that typically identified by government and university research communities....
The research integrated the postponement approach into service BPR by conducting a case study in catering services. It justified the effectiveness of postponement method for service BPR in dealing with the feature of customer contact in service process. And it also identified the role of modularization in postponement for service BPR project and the way modularization is applied. The paper then summarized...
China's logistics industry is still in its initial stage, the main problems facing is the high inventory cost. Reduction of inventory cost require internal procurement, production, warehousing, finance and other departments coordinating with different functions. In this paper, From the logistics concept, the writer brought forward strengthening inventory cost control measures in enterprise logistics,...
With the rapid development of socio-economic, the output of steel, which is one of the most important production materials in China, has been getting a significant growth. As a result of that, market puts forward new demands for steel logistics service. In this paper, traditional model of steel logistics is analyzed on the basis of a comprehensive previous studies. According to a new social required...
For the characteristics of the coal enterprises and the status quo of its supply management, with the idea of supply chain management, the main problems of the coal enterprise supply logistics system are analyzed, the logistics resources of coal enterprises are integrated, the supply logistics system of the whole enterprise is optimized, the supply logistics activities are rational organized, so that...
An integrated supply chain includes original manufacture and remanufacture. It can collect the used goods and close the material cycles. In this paper, an integrated supply chain with recycling are designed based on system dynamics. In this model, used goods can be collected by both collectors and retailers. The simulation proves that the choice of perfect collection style is based on the leader of...
Consumer return attracts more and more academic attention due to its rapidly expanding size, and a large portion of it falls into the category of false failure return, which refers to return without functional defect. In this paper, we exclusively consider profit results from exerting costly effort to reduce false failure returns in a reverse supply chain consisting of a retailer and a supplier. The...
In the circumstances of multi-assortment material supply, the supply chain supplier selection is a rather sophisticated problem. This paper uses a decomposing algorithm which has been widely used in the combinatorial optimization and makes improvement of it to realize the solution of the rational multi-supplier selection. Then, the paper tests the validity and feasibility of the new algorithm through...
The logistics services have the general characteristics of a project, so logistics services can adopt project management (PM) method. However, traditional project management (TPM) can't adapt to the changeable characteristics of logistics services. This article explains the reason that a new method of project management - adaptive project framework (APF) can be well adopted for logistics services,...
To find the industry characteristics of emergency in supply chain and to solve the problem of recognition about that. The paper established causation factor indexes system of emergency in supply chain based on systems analytical method, and at the same time, put forward a industry characteristics recognition model for emergency supply chain based on fuzzy clustering utilizing fuzzy similarity relation,...
Intensified globalization and consequent competitive pressures have reemphasized the importance of third party logistics (3PL). Logistics distribution management is the core of logistics management. In this paper, We study a mathematics method to determine the logistics distribution location for reducing the logistics costs.
To achieves the supply chains integration in construction has been advocated for a long time and it was deemed an effective solution to resolve many problems in construction. Because of the structure and current practice of the construction industry, however, the speed of integration is slow and the effect is unapparent. In this paper, the authors will present a conceptual framework of construction...
This paper aims at resolving conflicts in collaborative negotiation of a core enterprise with more than one upper negotiators and lower negotiators. First, the type and effect of conflicts in collaborative negotiation are analyzed. Furthermore, we design the Domain Propagation Algorithm based on Constraints Propagation and Constraints Loosening (DPACPCL) to resolve conflicts for collaborative negotiation...
A metagraph is a graphical construction that has been shown to be very useful to graphical visualization and quantitative analysis. In this paper, a Metagraph-based supply chain modeling method for discrete manufacturing industry was proposed. Then a set of metrics of the supply chain overall risk was given, and the algorithms for calculating the risk based on Metagraph model was proposed. Finally,...
In the course of globalization competitive pressure is rising in most industrial sectors. High quality products are basic prerequisites for companies of high wage countries to be present on the global market. Improved adherence to delivery date, increased flexibility despite to decreased production costs are some examples of the challenges to be managed just to keep current positions. In general,...
Supply chain management, in the scope of the described project, is about managing the flow of materials in a network of factories producing and transforming raw material into intermediate and final product, and the use of buffering instances such as storage tanks, silos and stockpiles. The system we present tries to reconcile the drivers of a supply chain: demand for final product and supply of raw...
Remanufacturing is an industrial process that makes used products reusable. Remanufacturing is one way for establishing a closed-loop supply chain. One of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. In addition, in this paper we are engaged in presenting a mathematical...
