In this paper, an integer quadratic programming model is proposed for workload balancing in the examination job assignment problem. The proposed model can be classified as part of the 'Generalised Assignment Problem' or GAP, which is known as an NP-hard problem. To solve the proposed model, a...

The main characteristic of today's manufacturing environments is volatility. Under a volatile environment, demand is not stable. It changes from one production period to another. To operate efficiently under such environments, the facilities must be adaptive to changing production requirements....

Although there are many studies in the literature that explain modern costing approaches including activity-based costing (ABC), the number of studies that present real life applications is very few. This is especially true for logistics and transportation applications. One of the main...
