Nowadays, industrial necessities claims global management procedures integrating information systems in order to manage and to use the controlled-processes information and thus, to assure a good process behaviour. These aspects aim to the development of fault detection and diagnosis systems and makingdecision systems. In this work, a reference model for fault management in industrial processes ...

The High-Variety, Low-Volume (HVLV) scheduling problem is one of the most arduous combinatorial optimization problems. This paper considers an interesting formulation of the HVLV scheduling problem using (max, +) algebra while periodic Preventive Maintenance (PM) is considered. Maintenance is time based since activities are periodically fixed: maintenance is required after a periodic time inter...

The objective of this paper is to study learning effects on maintenance outsourcing. We consider a situation in which a manufacturer offers a short-term outsourcing contract to an external contractor who is responsible for scheduling and performing preventive maintenance and carrying out minimal repairs when the process fails. The manufacturer’s payment to the contractor consists of a fixed amo...

We analyze a one machine scheduling problem subject to breakdowns and preventive maintenance. The primary objective in this work is to minimize the capacity loss due to rework resulting from breakdowns and potential capacity loss due to unnecessary maintenance. We propose a model where the timeline is split into two alternating regions as risk free and risky regions by assuming that the machine...

The use of the building is to support activities or as infrastructure for owners users in optimally carrying out their daily activities. expected be flexible following flow changes that occur later. This what underlies need maintenance In LPMP Dormitory building, have not been managed properly. order better, a management plan made on architectural and utility components building. Starting from ...

Consider the optimal control of a manufacturing system consisting of stages in which a single consumable good is produced in a random jump environment. At each stage of the manufacturing process there are workstations that can fail and be repaired. The workstations are assumed to have different operating parameters for a given stage. The mean time to failure for a given workstation, on a given ...

This work presents a methodology to assess maintenance teams in the determination of the degree of redundancy that an active component must have in order to minimize its system life-cycle cost and in the definition of the corresponding maintenance plan schedule. The minimal required data are three average costs and one reliability function. It is useful in a system’s design phase, since in this...

We propose in this study a hierarchical method for the problem of scheduling N jobs on M parallel machines where each machine should be maintained once during the planning horizon. The maintenance tasks should be continuously executed because the maintenance resources are not sufficient. Our objective is to find a schedule composed of the jobs and the maintenance tasks in which the total sum of...

We introduce the preventive maintenance scheduling problem with interval costs (PMSPIC), which is to schedule preventive maintenance (PM) of the components of a system over a finite and discretized time horizon, given a common set-up cost and component costs dependent on the lengths of the maintenance intervals. We present a 0-1 integer linear programming (0-1 ILP) model for the PMSPIC; the mod...
