An optimization approach for managing fresh food quality throughout the supply chain

One of the most challenging tasks in today's food industry is controlling the product quality throughout the food supply chain. In this paper, we integrate food quality in decision-making on production and distribution in a food supply chain. We provide a methodology to model food quality degradation in such a way that it can be integrated in a mixed-integer linear programming model used for production and distribution planning. The resulting model is applied in an illustrative case study, and can be used to design and operate food distribution systems, using both food quality and cost criteria.     

Regional trade and foreign currency regimes among the former Soviet Republics

The paper examines the problems arising from the adoption of national currencies in former Soviet Republics, and advances proposals to avoid excessive trade and output contractions. The move towards national currencies in many republics — though politically unavoidable and economically efficient in the medium term — is seen as having disruptive effects on interrepublican trade in the short term, with heavy losses of incomes and employment, which add to the costs of market transition. Mutual convertibility among the new currencies could allow some of the negative consequences on trade and production to be overcome, while in the event of mutual currently inconvertibility the effects on interrepublic trade could be disastrous and only some form of payments agreement could reduce the magnitude of the contraction. An intermediate currency regime which could sustain the level of income and employment would be based on the use of the Russian rouble as a regional means of payment. Such an event, however, would require as a pre-condition the stabilization of the Russian currency.

Supply optimization for the production of raw sugar

Based on a case study from Venezuela, the production of raw sugar is investigated. Ideally, sugar mills operate at a constant production rate. However, safety stocks of the raw material cannot be maintained as sugar cane quality deteriorates very rapidly. Sugar cane is therefore continuously sourced in diverse quantities and qualities from hundreds of geographically dispersed haciendas and supplied to the milling process. Furthermore, due to weather conditions changing throughout the year, tight time windows must be observed for harvesting.The approach presented in this paper aims at preserving a constant supply while minimizing the associated costs. The entire planning problem is structured in a hierarchical fashion: (1) cultivation of the haciendas, (2) harvesting, and (3) dispatching of the harvesting crews and equipment. The corresponding optimization models and solution procedures are introduced and applied to the case study problem.     

Shift designs for freight handling personnel at air cargo terminals

This paper presents an integrated mixed integer linear programming (MILP) model for determining manpower requirements and related personnel shift designs for the build-up and break-down of the unit load devices (ULDs) at the air cargo terminal to minimize manpower costs. To utilize the manpower resources efficiently, we implement a new mechanism for demand leveling. In addition, we consider the qualification hierarchy between build-up and break-down workers. A case study based on the real-life data shows that the model is useful for manpower planning at air cargo terminals and the integrated approach is far superior to a traditional two-stage approach.
