Manufacturing systems with forbidden early shipment: implications for choice of scheduling rules

Scheduling rule selection for the forbidden early shipment environment: a comparison of economic objectives

“…To a great extent this research was motivated by a recent article (Christy and Kanet 1990) comparing various scheduling rules in the FES environment based on tardy performance and a measure the authors define as mean system inventory. This study considers the more comprehensive economic objective of net present value (NPV) as well as those used by Christy and Kanet.…”

“…Also, the impact of different modelling assumptions was of interest in this study. The basic job shop model is described in Scudder and Smith-Daniels (1989) and uses different service time distribution assumptions (described in more detail in a later section) than Christy and Kanet (1990) who use exponential service times in their work. A combination of uniform and normal service time distribution are used in this study.…”

“…

In a recent paper, Christy and Kanet (1990) examined the performance of several dispatching rules in a forbidden early shipment environment. Their primary performance measure was time-weighted inventory value.

Due-date assignment and early/tardy scheduling on identical parallel machines

“…Overviews of this line of research can be found in articles by Baker [3] and Ragatz and Mabert [20] and the recent survey by Cheng and Gupta [6]. For the current focus on earliness as a performance criteria, the reader is referred as well to articles by Christy and Kanet [7] and Kanet and Christy 1171. Analytical studies of the problem, initiated by Panwalkar, Smith, and Seidmann [19], Seidmann, Panwalkar, and Smith 1211, are relatively new. As indicated in the survey on machine scheduling by Gupta and Kyparisis 11.51, they seem to point to an emerging trend of major significance.…”

Scheduling for stability in single-machine production systems

“…In manufacturing, job execution cannot start before auxiliary resources and tooling have been freed elsewhere in the shop and before the necessary parts and materials have been delivered to the processing site, and the due date communicated to the parties responsible for these prerequisites is normally the baseline starting time at the time of initial schedule development. 'Forbidden early shipment' restrictions at earlier stages in the production process (see, e.g., Christy and Kanet 1990, Kanet and Christy 1984, and Yano 1987) also constitute a source of this behaviour.…”
