Modern supply chains are expected to respond rapidly, effectively and efficiently to changes in the marketplace. Simultaneously there is the drive to achieve world class customer service levels coupled with minimum reasonable inventory (MRI). We thus have the classic conflict of interests between marketing, production and materials management. Marketing wants the complete product range availabl…
Studies have shown (1) that a company that ignores lead-time demand variability may suffer great financial damage, (2) that the gamma distribution provides the most common best fit to lead-time demand for a variety of inventory items, and (3) that a fixed lead-time demand assumption or a normal approximation to it will often yield significant errors because the true distribution is usually very…
In a system where two material flows with sequence dependency are matched, the use of real‐time information to monitor and control the sequencing buffer improves the system′s ability to schedule many different models, compared with a system with no information at all. In the latter case, the system is upset considerably when more than four different models enter the system. Shows how the …
The purpose of this paper is to begin to explore the phenomenon of time pressure in supply chain relationships.
Accepted logistics theory states that short lead times are consistent with high accuracy of customer service and low levels of inventory. Yet global or theatre based manufacturing strategies are lengthening lead times, extending supply chains and increasing risk of both excessive inventory and poor customer service. Logistics strategies to manage the conflicting interests of manufacturing and…
Logistics management has always been concerned with lead‐times. In particular, the order‐to‐delivery cycle has been seen as a major element in the customer service process. However, companies are now increasingly coming to recognise that the way in which ‘time’ is managed throughout the logistics system ‐ from procurement of materials through to the receipt of payment for goods so…
Namit and Chen recently created two algorithms to solve the inventory model for gamma lead-time demand without using tabulated values. However, other less complicated solutions that do not require the use of tabulated values are currently available. This note demonstrated the relative simplicity of those solutions and discussed some practical considerations.
