Design of Surveillance Planning Process for Thai Industrial Standard Product
Due to a progress on transportation and manufacturing technology, there are a large amount of products which customers can choose. These consumer products, which are not only local made products but also export products, need to be controlled by a proper standard. With this standard, products will be in a good quality which will also be safe for customers. Thailand Industrial Standard Institute (TISI) has a core mission in controlling product qualities. A standard named “TIS” (this abbreviation stands for Thailand Industrial Standard) issuing by TISI is used to certified consumer product qualities. Generally, there are two steps in the certificating process which are (1). audit and certificate and (2). annually monitor. A standard monitoring division 5 which is a member of TISI has a main function in annually checking certified manufacturers to ensure a quality level. This division is responsible for 192 manufacturers consisting of 520 certified products which cover 32 provinces in 7 regions. An objective of this paper is to design planning procedure for establishing monitoring schedule. In general, this schedule is created in September of every year. Moreover, this schedule must be created with respect to two types of constraints which are hard and soft constraint. The designed planning procedure comprises of 7 major steps which can be separated into 19 minor steps. Moreover, these 19 minor steps are arranged in a logical sequence. To ensure a performance of this planning procedure, the experiment on a practical case study are conducted. The results show that, with this procedure, a planning duration is decreased from 35 hours to 14 hours. Additionally, all constraints (both hard and soft constraints) are satisfied with this monitoring schedule.
