Researchers have given a lot of attention to the integrated vendor-buyer problem. Both deterministic and stochastic models on the subject are available in the literature. Most of the models have appeared with the need and requirement of a Just-in-Time (JIT) system environment. The close tie between a vendor and a buyer helps to deliver products in a shorter lead time with reduced inventory cost. Based on this idea, recently, some researchers have presented such a stochastic model with equal sized batch (part of a lot) transfer under controllable lead time. They have shown that their model provides a lower total cost for a numerical problem. To enrich the JIT system literature, considering transportation cost of a batch, this article develops an alternative model of the problem with equal or unequal sized batches transfer under controllable lead time. Then it develops a heuristic solution technique of the model and applying it solves the same numerical example to show a reasonable cost reduction.
