This research deals with the development of Autonomous Distributed Manufacturing Systems (ADiMS) Concept and an example of its application in the casting industry. ADiMS is a manufacturing system concept developed to increase the flexibility of the system. In ADiMS, each of the manufacturing system elements (holon) had been modelled as an intelligent element with the result that each element ha...

This paper proposes an approach for optimal design of multilevel systems under uncertainty. The approach utilizes the stochastic extension of the analytical target cascading formulation. The reliability of satisfying the probabilistic constraints is computed by means of the most probable point method using the hybrid mean value algorithm. A linearization technique is employed for estimating the...

Firms have invested over $15 billion in the past three years on new information technology and software in their manufacturing plants. In this study, we document how the implementation of new types of manufacturing practices has impacted the types of information technology investments in manufacturing plants. We present a conceptual model to develop hypotheses about relationships between manufa...

The gas force due to the combustion in the cylinder of an IC engine will cause the piston to move with primary motion and secondary motion. The primary motion of the piston from TDC to BDC is linear in nature. This motion is desired for translation of motion of engine components. Secondary motion is due to the transverse motion of the piston while piston moving from TDC to BDC and vice-versa. T...

This work proposes a new configuration of liquid piston compressors and methodology for their optimization, with special attention to heat removal from the compressing gas, in order minimize mechanical required compression process. The adopted approach starts solution governing equations through 0D model (lumped approach). A correlation transfer coefficient is presented calculate sensible gas c...

This paper takes dynamics analysis on the piston and the dynamic lubrication theory on the skirt and the ring of piston as the basis. Using AVL Glide software, through the establishment of the analysis model of the piston secondary movements, this study focuses on the effects of the crankshaft bias on piston secondary movements’ characteristics. This paper takes 5 different offsets, by comparin...

This paper describes the behavior of a rolling piston in a rolling piston type rotary compressor under various operating conditions. Kinematic behavior of the rolling piston is discussed with attention to the friction forces acting on the rolling piston and the vane. Emphasis is on the following simulation approach. (1) The equation of motion of the rolling piston is solved in conjunction with ...

This study examined the relationship between lean job design and work-related musculoskeletal disorder (WMSD) risk factors. Repetition, force, and posture were assessed for a sample of 56 production jobs across departments at a lean automobile-manufacturing plant and compared to 56 similar jobs at a traditional automobile-manufacturing plant. The results showed greater productivity in the lean ...
