To fully maximise profitability, strategies regarding reverse logistics must be analysed and implemented. This study researches several such logistics constructs such as resource commitment, production route efficiency and others. A thorough survey instrument was developed and mailed in effort...

This paper presents a state transition based formal framework for a new search method, called Evolutionary Ruin and Stochastic Recreate, which tries to learn and adapt to the changing environments during the search process. It improves the performance of the original Ruin and Recreate principle...

In 2008, the hypoxic zone in the Gulf of Mexico, measuring 20720 km2, was one of the two largest reported since measurement of the zone began in 1985. The extent of the hypoxic zone is related to nitrogen and phosphorous loadings originating on agricultural fields in the upper Midwest. This...

This paper discusses the estimation of models of the term structure of interest rates. After reviewing the term structure models, specifically the Nelson-Siegel Model and Affine Term- Structure Model, this paper estimates the terms structure of Treasury bond yields for the United States with...

This paper deals with the economics of a closed-loop supply chain and the decision-making in a hybrid manufacturing system. We develop analytic models and quantify the potential profits gain generated by such a hybrid system that collects, remanufactures, and remarkets the end-of-use products as...

Based on environmental, legal, social, and economic factors, reverse logistics and closed-loop supply chain issues have attracted attention among both academia and practitioners. This attention is evident by the vast number of publications in scientific journals which have been published in...

This paper examines reverse logistics practices in the pharmaceutical manufacturing industry in Ghana. The sample were selected on hierarchical levels using stratified sampling methods. With a 100% response rate, data gathered from both primary and secondary sources were analyzed using...

In present days, the waste management, especially municipal waste, becomes more important than before. Together with the economy development, higher numbers of products offered and bigger customer’s demand, the level of waste generated by humans are getting higher as well. Non-used waste are...

Fast development of automotive industry in Poland in recent years involves the need for rational waste management from the destruction and exploitation of vehicles. Rising number of new cars in Poland and existing age structure of the domestic park of vehicles will contribute to the increase...
