This paper formulates a non-linear integer programming model to solve a maintenance workforce sizing problem with a productivity improvement goal. This problem is modelled in a bi-objective framework that minimises the number of maintenance personnel while maximising their productivity levels. Inputs into the optimisation model include monthly and routine maintenance periods, volume of producti...

We analyze the integrated tactical capacity planning of spare parts supply and workforce allocation in maintenance logistics of advanced equipment. The equipment time-to-failure, spare parts replenishment time, and equipment repair time are random and independent of each other.

Most of the research on aggregate production planning has been focused on discrete parts manufacturing models. In environments where intermediate inventory cannot be stored, and multiple products are produced simultaneously using complex con$gurations of production machines, these models may produce erroneous results. In this paper, we present a con$guration-based formulation for one such manuf...

Traditionally, the three important manufacturing functions, which are process planning, scheduling and due-date assignment, are performed separately and sequentially. For couple of decades, hundreds of studies are done on integrated process planning and scheduling problems and numerous researches are performed on scheduling with due date assignment problem, but unfortunately the integration of ...

Maintenance and support may account for as much as 60 to 75% of the total lifecycle cost of a manufacturing system. This paper presents a review on the predictive maintenance approaches, methods and tools in manufacturing systems and proposes an integrated predictive maintenance platform. This platform consists of three pillars, namely data acquisition and analysis, knowledge management, and a ...

Every industry is dependent on some type of asset that keeps the business in business be it a computer, a CNC, or a megawatt transformer. In a large enterprise, reducing costs related to asset maintenance, repair, and ultimate replacement is at the top of management concerns. Downtime in manufacturing ultimately results not only in high repair costs, but in customer dissatisfaction and lower po...

This paper will review all the Total Productive Maintenance (TPM) Pillars, TPM Implementation methodology and the contribution of TPM towards improving manufacturing performance.. It will also focus on calculating the Overall Equipment Effectiveness (OEE) in one of the two wheeler automobile Industry in India. The relationship between various TPM implementation dimensions and manufacturing perf...

Increased reliance on agile manufacturing techniques has created a demand for systems to solve integrated process-planning and production-scheduling problems in lasge-scale dynamic environments. To be effective, these systems hould provide useroriented interactive functionality for managing the various user tasks and objectives and reacting to unexpected vents. This paper describes the mixed-in...
