A heuristic to control integrated multi-product multi-machine production-inventory systems with job We present a heuristic that minimizes the relevant costs by making near-optimal production and inventory control decisions while target customer service levels are satisfied. The heuristic is tested in an extensive simulation study and the results are discussed.

Felicitous

Planning order releases for an assembly system with random operation timesjective is to choose starting times for different operations in order to minimize the total expected costs. We suggest an approximate decomposition technique that is based on repeated application of the solution of a simpler single-stage problem. The performance of our approximate technique is compared to exact results in a numerical study.

Automated flow lines with shared bufferction rate as demonstrated by simulation experiments. Also, a preliminary economic evaluation on a real case has been carried out to estimate the profitability of the system comparing the increase of production rate, obtained with the new system architecture, with the related additional cost.

Performance analysis of parallel identical machines with a generalized shortest queue arrival mechan obtained from so-called flexible bound models, and they provide a powerful tool to efficiently determine the mean waiting time. The bounds are used to study how the mean waiting time depends on the amount of overlap (i.e. common job types) between the machines.

Stochastic cyclic flow lines with blocking: Markovian modelstion and blocking probabilities through the adjacent submodels. We discuss performance characteristics including comparison with random order processing and effects of the job variation and the job processing sequence. We also report the accuracy of our proposed method.

Dilemmas in factory design: paradox and paradigmms for which there are crucial dilemmas and correspondingly deep-seated underlying paradoxes. These paradoxes, however, give rise to novel paradigms which can bring about fresh approaches as well as insights into their solution.

Lean buffering in serial production lines with non-exponential machines system) is analyzed for the case of serial lines with machines having Weibull, gamma, and log-normal distributions of up- and downtime. The results obtained show that: (1) the lean level of buffering is not very sensitive to the type of up- and downtime distributions and depends mainly on their coe

Analysis of flow lines with Cox-2-distributed processing times and limited buffer capacity analyzed exactly and a larger flow lines are evaluated through a decomposition into a set of coupled two-machine lines. Our results are compared to those given by Buzacott, Liu and Shantikumar for their “Stopped Arrival Queue Modell”.
