Abstract
The application monality can better meet the needs of customers,
improve the rapid reaction capability, implement inventory cost optimization, and has
been a main technique for mass customization production. The service level, how much
customers needs the enterprise achieved to meet, has an important impact on corporate
efficiency, and even plays an important role on the long-term development of enterprises.
Therefore, studying monality strategy monality
inventory model based on the service level constraints has great significance to reducing
corporate costs and improving production efficiency.
On the basis of early scholars’ research results, this paper established ponent
commonality inventory models with service level constrain. ponent
commonality inventory models with service level constrain include aggregate service level
models and product-specific service level models. Use the probability to formulate the
specific service level, and obtain the expressions through the products demand. With all
constrains, we set up the inventory models both monality and without
that. The plicated models are that with PSL constrains, including two kinds of
models based on whether of not the products are prioritized. In the prioritized s
