Recent software developments in system modelling via transfer function analysis now enables a much broader understanding of the dynamics of aggregate planning to be gained. In particular it opens up the possibility of exploiting filter theory as a focal point during algorithm design. This is particularly attractive in view of the fact that we have established, via transfer function models, that...

In this paper, we introduce a linear mathematical model for the Aggregate Production Planning problem for a forestry company operating several sawmills. Considering different types of raw materials, different production parameters, and a group of sawmills, the industry tries to identify the best levels of production, of subcontracting production, and of inventory to satisfy the demand for diffe...

In the Aggregate Production Planning (APP) the manager considers simultaneously conflicting objectives such as total cost, inventories level, workforce fluctuation, and utilization level of the physical facility and equipment. The goals associated with these objectives may be uncertain in nature. The aim of this paper is to develop a Goal Programming (GP) model where the goals and the right-han...

This work focuses on the supply chain tactical planning problem in an uncertain and disrupted environment. Aspart of point-to-point relationships, we propose an optimal and reactive tactical planning approach of a supply chainlink in the presence of uncertain parameters and disturbances.Our approach is based on a two-level decision structure. The first level performs an aggregat...

Response time on orders of customers is becoming a critical issue to achieve a competitive advantage. A major problem is a lack of strategic perspective of information systems. A need for adequate tools and methodologies to model the system structure and to define integrated requirements is a must for the manufacturing enterprises. This paper presents a study of implementing Zachman Framework Z...
