Among both inventory theorists and practitioners, it is common use to include an opportunity cost rate in the holding cost rate. In that way, the cost of capital can be roughly incorporated in an average cost (AC) inventory model. The traditional way for calculating the opportunity cost rate is to multiply the interest rate (or discount rate) by the marginal cost for producing/ordering an item....

This paper proposes an innovative uncertainty management using a stochastic model to formulate logistics network starting from order processing, purchasing, inventory management, transportation, and reverse logistics activities. As this activity chain fits well with Markov process, we exploit the very principle to represent not only the transition among various activities, but also the inherent...

Smog in industrial zones, the depletion of the ozone layer, and global warming demonstrate exemplarily the harmful impact of business activities on environmental systems and the societies that act within them. Therefore, customers and many governments around the world are developing a more conscious and respectful attitude toward the environment, turning environmental concerns into a central el...

Along with the continual development of the social economy,there is an increasing demand for natural resources in the worldwide society. Meanwhile,social production and consumption often produce a large amount of castoffs and returns. It is found that reasonable disposition and reclamation of the castoffs and returns can not only improve using efficiency of resources and reduce waste of resourc...

In order to solve closed-loop logistics network design problem in the low-carbon economic environment, in this paper, queuing theory is used to calculate the amount of storage of reverse logistics nodes and interval number is used to describe the uncertainty of the logistics network, a bi-objectives logistics network design model which minimum the total cost and carbon emissions of logistics ne...

In this work the suppIy-chain co-ordination in the virtual enterprise environment is subject of deeper analysis. The system developed by UFSC DBPMS for the management of distributed business process is presented and some basic concepts for its definition and development are detailed. The DBPMS provides means for getting, analyzing, making available and managing the information from and about a ...

Manufacturing is a major driving force and an important pillar for national economic development .It is an important source to create national income. Currently the low level of logistics industry development significantly restricted prosperity and development of manufacturing, and affected the overall competitiveness of the supply chain. The paper firstly explains the relevant research about i...

In fashion business customer demand is changing due to fashion trends and new designs. Time from customer demand to customer demand fulfillment is essential for company’s ability to compete in the fashion retailing business. During the last 20 years there has been a dramatic technical development in the production of flat knitted garments. This has made it possible to rationalize design and pro...

We consider a logistics spot market where the transportation orders from a number of firms are matched with two types of carriers through a reverse auction. In the spot market, local carriers compete with in-transit carriers that have lower costs. In order to analyze the effects of implementing a logistics spot market on these three parties: firms, local carriers, and in-transit carriers and al...

In this work the design of a reverse distribution network is studied. Most of the proposed models on the subject are case based and, for that reason, they lack generality. In this paper we try to overcome this limitation and a generalized model is proposed. It contemplates the design of a generic reverse logistics network where capacity limits, multi-product management and uncertainty on produc...
