aggregate production planning (app) is one of the most important issues carried out in manufacturing environments which seeks efficient planning, scheduling and coordination of all production activities that optimizes the company's objectives. in this paper, we develop a mixed integer linear programming (milp) model for an integrated aggregate production planning system with closed loop su...

Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...

HEDIS Scores Improve Dramatically In past years, the National Committee for Quality Assurance has used the annual release of its “State of Managed Care Quality”report to goad health plans into better HEDIS performance. Plans that do well are stroked; minimal improvement is called not good enough; and those that do not participate in HEDIS, that are not accredited by NCQA, or that do not report ...

Enterprise resource planning (ERP) maintenance and upgrade activities are receiving much attention in ERP-using organizations. Annual maintenance costs approximate 25% of initial ERP implementation costs, and upgrade costs as much as 25-33% of the initial ERP implementation. Still, the area of ERP maintenance and upgrade is relatively new and understudied as compared to ERP implementation issue...

This paper addresses a support information system for the planning of aircraft maintenance teams, assisting managers in delivering an on time. The developed teams is computer application based mathematical programming problem written as minimization one. initial decision variables are positive integer specifying allocation available technicians by skills to teams. objective function nonlinear b...
