A deterioration of due-date reliability is often attributed by planners to external causes rather
than to their own planning behavior. Particularly, planners tend to underestimate the effects …

If order due dates are missed, a frequent reaction of production planners is to adapt planned
lead times. How often and to what extent updates are reasonable has previously been …

The aim of production planning and control is to ensure the achievement of the logistic
targets of high due date reliability, low lead times, high capacity utilization, and low WIP …

A fundamental construct of most planning systems is the planned lead time. A planned lead
time is a control parameter that refers to the planned amount of time for a production …

Reducing lead time variability of production systems has been shown to be advantageous,
enabling constant flows and improved on time production. Nevertheless, fluctuating order …

Many companies in practice want to dynamically adjust planned lead times in their
production planning and control systems in response to demand fluctuations. But for …

Updating planned lead times in response to changing workload levels leads to erratic
ordering behaviour, resulting in even larger variability in the workload levels and flow times …

In this study, our concern is to show the effect of updating lead times on the performance of a
two-level hierarchical planning system. Lead times are updated by taking periodic …

Projects for leadtime reduction in production system have to be evaluated economically with
respect to their impact on logistic costs and customer service. In this paper a procedure for …

In intermittent production systems, job shops, manufacturing lead times are often long and
variable, yet only about 10% is due to the actual processing time. This is a major difficulty in …
