International Journal of Product Development (IJPD), Vol. 7, No. 3/4, 2009

Abstract: Quality is considered to be the most important factor in the world market competition. Increasing quality, however, increases the cost. Thus, the main objective of the industry achieving higher quality with less cost is essential and extremely difficult to obtain. One of the effective techniques used to overcome this difficulty is the acceptance sampling plan. Therefore, a complete review of all sampling plans including single, double, sequential, chain and continuous sampling is made here. Also, computer programs are constructed for all of these plans and incorporated in one package, coded in Visual Basic Language. The package contains guidelines to assist the user to select the proper sampling plan according to his/her objectives, and probabilities of Risk I and Risk II types. Unequal subgroups are also included, in order to help the user to construct the standardisation control charts. The package is friendly, flexible and interactive in nature. It showed excellent performance and displayed similar results to those found in the literature. Finally, typical illustrative examples and results are given, including some applications from the powder technology.
