Humanitarian organizations pre-position relief items in pre-disaster and distribute them to the affected areas in post-disaster. Improper planning of emergency operations causes more deaths in post-disaster. In this paper, the problem of relief item pre-positioning and multi-period distribution planning is addressed considering lateral transhipment among distribution centres to improve the effi...

Planning problems over multi-period horizons occur in arc routing but are neglected by OR researchers. This paper presents these new problems, a classification and a hybrid GA able to tackle the planning and scheduling levels simultaneously.

This study aims to develop a multi-period distribution system design model that provides an integrated view of the various costs, service quality and budget concerns within the planning horizon, as well as computationally feasible methods for obtaining solutions in realistic situations. The key design decisions considered in each period are: the number and location of distribution centers in t...

Developing an efficient heuristic algorithm to solve a supply chain operations planning model is the main purpose of this paper. The model considers multi period supply chain planning with capacitated resources. The concept of multi period capacity consumption has been developed recently at the context of supply chain management that realizes resource planning at a supply chain. Because of cons...

The location planning of emergency medical service (EMS) stations is crucial, especially in populated cities with heavy traffic conditions like Istanbul. In this paper, we propose both a single-period and a multi-period problem, two variants of the well-known Maximal Covering Location Problem, which require two types of services in the location planning of the EMS stations. The objective of the...
