Traditionally, answer the questions of “when to replenish”and “how many to replenish”using varies forecasting methods are commonly seem in the supply chain inventory management. However, the uncertainty with changeful demand often makes various kinds of prediction methods became less efficient. To solve the problem, the demand-pull and buffer management of TOC replenishment method developed by ...

This paper presents an online energy management system based on a virtual energy provisioning (VEP) concept. VEP is a novel demand side management inspired by the lean supply chain technology. It aims to control the process of energy generation, delivery, and consumption under the mechanism called “order-then-production” principle. This means electricity should be ordered by end consumers in ad...

Sustainability in the supply chain means pushing the supply chain to focus on social, economic and environmental aspects, and addressing the existing problems in the traditional supply chain. Considering the importance of evaluating supply chain networks, especially in the field of perishable commodities, this paper aimed to design a mathematical model for the reverse supply chain of perishable...

managing the supply chain plays an important role in creating competitive advantages for companies. adequate information flow in supply chain is one of the most important issues in scm. therefore, using certain information systems can have a significant role in managing and integrating data and information within the supply chain. pharmaceutical supply chain is more complex than many other supp...

The supply chain management (SCM) consists of the integration of the business logistics management processes involving not only units within an enterprise but also across units belonging to both upstream and downstream partners, such as suppliers, customers, and logistics service providers. According to the council of logistics management (CLM, 1999), the set of activities to be managed include...

In today’s globalization, the success of an industry is dependent on cost effective supply chain management under various markets, logistics and production uncertainties. Uncertainties in the supply chain usually decrease profit, i.e. increase total supply chain cost. Demand uncertainty and constraints posed by the every echelon are important factors to be considered in the supply chain design ...

In this lecture we present a few key results in production planning with known time-varying requirements under convex or concave production costs. Convex production costs arise when we need to utilize increasingly more expensive resources to achieve higher levels of production. As an example, consider a factory with a regular workforce. If demand is beyond the capacity of the regular workforce,...

Marc Lambrecht Faculty of Business and Economics, Research Center for Operations Management, K.U.Leuven, Belgium [email protected] The health care sector is a fast-growing segment of GNP in almost every economy. No wonder that we witnessed a tremendous increase in research to improve both medical practice and management practice. Patient flow management is an example of such a man...
