CHAPTER 1
INTRODUCTION
1.0 Preliminary
This chapter presents the overall review of the study including the background of the study, problem statement and objectives of the study. Afterward, the background of companies and products are also described. Lastly, the expected outcome is explained in this chapter.
1.1 Background of the Study
Make-to-order (MTO) and Make-to-stock (MTS) are the production operation systems that are used in the industries. Usually, overcapacity and capacity shortage are occurred during the production system and will affect the balancing of the demand supply of the product. In order to reduce imbalance problem in the production stability, MTO and MTO strategies were applied the industries.
2 time and will be the just in time (JIT) in delivering the product to the customer. MTO also have the main operational issues such as capacity planning, order acceptance and system, it depends on the specific things such as the process of the product, the material and the capacity of the product.
3 capacity and overcapacity occurred at this company. The excess capacity occurred because of the production outputs is more than the demand quantity.

1.3 The important of Study
The importance of the study is to determine the characteristics of the MTO and MTS operation system that could give impact to product variable, production stability and product quality. The critical factors that contribute to the increment inventory level could be determined after.
