Maintenance management is the effective and economical use of resources to keep equipment in, or restore it to, a serviceable condition. In this paper, maintenance considerations are introduced during product design using a game theoretic approach. Specifically, a product designer and a maintenance manager are modeled as two players in a Leader–Follower game, and strategies for designing produc...

Object orientation in modeling, i.e. the possibility to structure a model according to the objects present in the system under consideration, promotes reuse and simplifies maintenance. This paper is mainly devoted to composite language constructs, like matrix notation, multiple inheritance and generic class parameters, that are introduced in order to further facilitate reuse and maintenance of ...

Purpose: Today, human resources are considered as one of the most important resources of any organization. Therefore, the current research was conducted with the aim of modeling the complications of the retention, maintenance and education system of human resources. Methodology: This study was mixed means combination of qualitative and quantitative researches. The population of the qualitative...

Abstract Maintenance policy selection for vessel equipment is a multiple criteria decision making. To ensure security, reliability and efficiency of vessel equipment, a maintenance decision model based on risk, availability and cost was proposed according to the characteristics of vessel equipment maintenance. For modeling, analytic network process (ANP) has been employed. And the maintenance p...

A hybrid method, applied thermal modeling and temperature measurement, is proposed to estimate the junction temperature (Tj) of high-power light-emitting diodes (LEDs) at system level, and further project long term lumen maintenance of LED lamps. First, 3D finite element modeling on commercial LED lamps is performed based on lamp structure and material information to find a steady and reliable ...

In this paper we describe ongoing research in the areas of maintenance and warranty decision-making for gas turbines used in power plants. We first frame the problem within a larger context of equipment monitoring, diagnostics and maintenance. We then focus on describing and modeling economic issues related to warranty maintenance service from the perspectives of both the consumer (power plant ...

We first frame the problem within a larger context of equipment monitoring, diagnostics and maintenance. We then focus on describing and modeling economic issues related to warranty maintenance service from the perspectives of both the consumer (power plant owner) a...

The maintenance became one of the strategic industrial functions. Far from being stabilized today, it progress by introducing the new management methods and the technological development of the production equipments, in particular in the measurement and the control operation. All these factors modify the organization modes of the maintenance function, which converges more and more towards a coo...

Applications and services deployed across complex, multi-layered architectures require comprehensive modeling frameworks to effectively manage the software lifecycle—from concept to code. The typical process evolves from high-level concepts to requirements and specifications and then design, development, deployment and maintenance. Too often the modeling process breaks with the code, especially...

scheduling has become an attractive area for artificial intelligence researchers. on other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. a maintenance program may be considered as the heath care of manufacturing machines and equip...
