collection of municipal solid waste (msw) accounts for a significant proportion of most municipal budgets, and has drawn some degree of researchers‟ interest. this study was conducted in ota, southwest nigeria, to explore the use of visual basic program as an innovative tool to select the most economic haulage system among three systems found in literature (conventional-, modified- and stationa...

This paper discusses the impact of collection cost structure on the optimal reverse channel choice in decentralized uncoordinated supply chains. Using collection cost functions that capture collection rate and collection volume dependency, we show that the optimal reverse channel choice is driven by how the cost structure moderates the manufacturer’s ability to shape the retailer’s sales and co...

This note discusses the impact of collection cost structure on the optimal reverse channel choice of manufacturers who remanufacture their own products. Using collection cost functions that capture collection rate and collection volume dependency, we show that the optimal reverse channel choice (retailerversus manufacturer-managed collection) is driven by how the cost structure moderates the ma...

A collection of landmarks is complete if the cost of a minimum-cost hitting set equals h and there is a minimumcost hitting set that is an optimal relaxed plan. We present an algorithm for generating a complete collection of landmarks and we show that this algorithm can be extended into effective polytime heuristics for optimal and satisficing planning. The new admissible heuristics are compare...

Collection of waste is an important logistic activity within any city. In this study, a mathematical model is proposed in order to reduce the cost of waste collection. First a mixed-integer nonlinear programming model is provided including a waste collection routing problem, so that, there is a balance between the distance between trashcans, and the similarity of the trashcans in terms of th...

the objective of this study was to develop a new optimal parallel algorithm for matrix multiplication which could run on a fibonacci hypercube structure. most of the popular algorithms for parallel matrix multiplication can not run on fibonacci hypercube structure, therefore giving a method that can be run on all structures especially fibonacci hypercube structure is necessary for parallel matr...

Connectivity-Based Garbage Collection is a new family of garbage collection algorithms that are based on potential object connectivity properties. Objects are placed into partitions based on a static connectivity analysis. When the program needs memory, the collector can choose a set of partitions to do a garbage collection on. This choice should maximize the expected benefit in reclaimed memor...
