Excessive downtime remains a problem for many organisations, particularly those using complex capital intensive manufacturing processes. To counter this, many use computerised management systems to support various aspects of their maintenance activities including breakdown diagnosis. This paper describes research that has been undertaken to investigate the effectiveness of maintenance informati...

This paper describes the development of a computerized line maintenance simulation model for strategic manpower planning at Continental Airlines for one of their major maintenance stations at Newark airport. The simulation model provides guidelines to the development of enhanced staffing models and a better understanding of resource requirements on a daily basis. The proposed simulation model c...

This paper considers the single-machine problem with job release times and flexible preventive maintenance activities to minimize total weighted tardiness, a complicated scheduling for which many algorithms have been proposed in literature. However, considered problems are rarely solved by genetic (GAs), even though it has successfully various combinatorial optimization problems. For problem, w...

Symmetric mathematical programming is used to analyze the optimality of balancing workloads t~ maximize the expected production in a single-serve~closed queuing network model of a flexible manufacturing system (FMS). In particular, using generalized concavity we prove that, even though the production function is not concave, balancing workloads maximizes the expected production in certain types...

Purpose – This paper aims to develop path-planning techniques that support a general selective disassembly planner in a virtual reality environment. Design/methodology/approach – The paper presents an automatic selective disassembly planning and two path-planning techniques that support it. The first one is based on single translations, while the second is based on the generation of a random se...

DONES is planned to operate on a continuous basis with only two beam stop periods per year for maintenance. The operational availability 70 %, which calls carefully analyzed preventive purpose of the research propose realistic and comprehensive logistics maintenance plan. All activities are included in Maintenance Matrix based Plant Breakdown Structure project. This creation plan that will lead...

In this paper, we consider a multi-period, multi-product production planning problem where the production rate and the customer service level are random variables due to machine breakdowns. In order to determine robust production plans, constraints are introduced in the stochastic capacitated lot-sizing problem to ensure that a prespecified customer service level is met with high probability. T...
