PT. ABC is a company engaged in the manufacture of Dolomite Fertilizer. The number requests greater than amount production. Due to fluctuations that tend increase, this occurs due lack capacity at workstation. Therefore, it necessary calculate requirements planning analysis for each work station know company's needs. research aims identify shortage/excess production and provide proposals balanc...

Global competition and changing customer requirements are putting major challenges in the production planning and control systems of manufacturing enterprises. Production planning and control requires robust methods able to cope with demand variability, processing times variability, routing sequences, resource availability, etc., between other sources of variation. Production planning and contr...

The use of 3D computer-aided design (CAD) models to support construction project planning has been increasing in the previous year. 3D CAD models reveal more planning ideas by visually showing the construction site environment in different stages of the construction process. Using 3D CAD models together with scheduling software to prepare construction plan can identify errors in process sequenc...

This paper develops a method for solving the single product multi-period production-planning problem, in which the production and the inventory costs of each period arc concave and backlogging is not permitted. It is also assumed that the unit variable cost of the production evolves according to a continuous time Markov process. We prove that this production-planning problem can be Stated as a ...

The question of the sustainability of IT-dependent com considerably less attention, and much of that attention ha assumption usually underlying this pessimistic view is that sustainable competitive advantage because competitors ca replicate virtually any of its applications. We suggest inst quest for sustainable competitive advantage risks oversimp potential strategic contributions of advanced ...
