Abstract

Conventionally, all Economic Ordering model tacitly assumes that the immediate payment with the shipment of the products. But, in practice, the vendor may allow permissible delay in payments to the buyer. Quality management with minimized cost is the crucial factor for organization’s growth. Inspecting 100% of the products are time-consuming and costly especially when it involves destructive testing or inspection cost is huge. Acceptance sampling plan by attributes provides an effective solution to minimize the cost and consumes less time. Quick Switching System-1with two intensity of inspection is ease to apply as it enables instantaneous switch between normal and tightened inspection depends on the quality of the product. With more reliable products normal inspection is employed and vice versa.QSS-1 plan with minimum sum of risks carries another advantage of reducing the consumer and producer’s risk. With the application of the QSS-1 through minimum sum of risks on the EOQ model with permissible delay in payments buyer and vendor gets minimized cost, minimized risk and less time consuming process.

Highlights

  • Acceptance sampling or statistical product control adheres to the process of randomly inspecting a sample of products and determines whether to accept the entire lot based on the results or reselling or rejection of the lot, returning to the producer, screening and scraping

  • American National Standards Institute/American Society for Quality Control Standard A2 (1987) defines acceptance sampling as the not-accept are based on the results of the inspection of samples

  • Montogomery (2009) cited that Dodge and Romig in 1928 developed acceptance sampling procedures at Bell Laboratories testing the bullets. It is a product control techniques applied to determine whether the incoming raw materials or outgoing final products fit to the described quality standards

Summary

Introduction

Acceptance sampling or statistical product control adheres to the process of randomly inspecting a sample of products and determines whether to accept the entire lot based on the results or reselling or rejection of the lot, returning to the producer, screening and scraping. The intent of this paper is to develop mathematical model for EOQ model incorporating Quick Switching System-1 with single sampling plan as reference plan under the conditions of Poisson distribution through minimum sum of risks with permissible delay in payment. 2. Procedure for selection of Quick Switching System-1 with single sampling plan through minimum sum of risks The tables constructed is used to select the acceptance number for specified p1 and p2 with minimum sum of producer’s and consumer’s risks. Against the predetermined value of the operating ratio p2/p1, the table provide the parameters of the sampling plans and the associated producer’s and consumer’s risks in the table against the product of sample size and acceptable quality level (np[1]). The expected total cost becomes, When T≥M, E(TC1)
