SM (Smart Manufacturing) is a broad category of manufacturing that employs computer-based integrated system, with higher end new adaptability and quick change in design structure, along digitalization effective workforce training. It necessary to incorporate techniques the system adapt changes present system. Smart factories increase output unit, quality, consistency maintenance by satisfaction...

The cost of an optimal delete relaxed plan, known as h+, is a powerful admissible heuristic but in general intractable to compute. In this paper we examine the problem computing h+ by encoding it MAXSAT problem. We develop new that utilizes constraint generation support computation sequence increasing lower bounds on h+. show close connection between computations performed recent approach for s...

A manufacturing feature can be defined simply as a geometric shape and its manufacturing information to create the shape. In a feature-based process planning system, feature library that consists of pre-defined manufacturing features and the manufacturing information to create the shape of the features, plays an important role in the extraction of manufacturing features with their proper manufa...

Today’s manufacturing plants are equipped with heterogeneous software systems for different types of tasks, both manufacturing operations and factory planning. On the operating level software systems are neither yet integrated and thus support separate tasks such as production monitoring, sequence planning, work piece identification, maintenance order management, worker information and others. ...

Increasing attention is being paid to complete machining, i.e., machining of the whole part in a single machine tool, in the metal working industry. For this purpose, complex machine tools equipped with machining components, such as multiple spindles and turrets have been developed by leading machine tool builders. The efficiency of complex machine tools is largely dependent on how the machinin...

A workforce management problem in service industries is to determine how to allocate employees to jobs such that the service demand can be satis ed as much as possible at minimum cost. It has been studied in the Operations Research, Genetic Algorithms and other areas. Recently, Constraint Logic Programming (CLP) has provided a declarative and powerful tool which has been successfully used to so...

Considering the present business competitive scenario, the automotive industry is under pressure to achieve higher productivity. A high level of performance and quality standard could be achieved through improving the Overall Equipment Effectiveness (OEE) of the equipment in an automotive industry. Thus, the aim of this study is to investigate the performance measurement through OEE theory in a...

This paper presents a special case of integration of the preventive maintenance into the repair/replacement policy of a failure-prone system. The machine of the considered system exhibits increasing failure intensity and increasing repair times. To reduce the failure rate and subsequent repair times following a failure, there is an incentive to perform preventive maintenance on the machine befo...

This paper presents a new bridge management system (J-BMS). It is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. The proposed J-BMS not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. In this ...
