Chapter 1 Overview
1.1 Introduction
Manufacturing businesses need to come with new products in order to survive m afierce competitive environment. Product quality and reliability are importantcompetition factors. This book focuses on models, tools, and techniques to helpmanage quality and reliability for manufactured and new products.
This chapter is organized as follows. Section l.2 briefly discusses relevantconcepts of product. Section l.3 presents notions of product reliability and productquality. The objective, scope, and focuses of this book are presented in Sect. 1.4.Finally, we outline the structure and contents of the book in Sect. 1.5.
1.2 Product and Product Life Cycle
1.2.1 Product
From a marketing perspective, a product is anything that can be offered to amarket that might satisfy a want or need; and from a manufacturing perspective,products are purchased as raw materials and sold as finished goods. Based on thetype of consumer, products can be classified as consumer durables and industrialproducts. The former is for consumers e.g., cars and the latter is for a businessand hence often termed as business-to-business product e.g., engineeringmachineries.
A product can be a single component or a complex system comprised of manycomponents. For the latter case, one can decompose a product into a hierarchy structure. A typical decomposition of a product includes six hierarchical levels,i.e., material, part, component, assembly, subsystem, and system.
1.2.2 Product Life Cycle
The concept of product life cycle PLC is different for manufacturers and con-sumers [4]. From the perspective of the manufacturer, the PLC refers to the phasesof a product''s life, from its conception, through design and manufacture to post-saleservice and disposal.
On the other hand, from the perspective of the consumer, the PLC is the timefrom the purchase of a product to its discarding when it reaches the end of its usefullife or being replaced earlier due to either technological obsolescence or the productbeing no longer of any use. As such, its life cycle involves only the following threephases: acquisition, operations and maintenance, and retirement that leads toreplacement by a new one.
1.2.3 Technology Life Cycle of a Product
From the perspective of marketing, the PLC involves four phases see Fig. 1.1:. Introduction phase with low sales
Growth phase with rapid increase in sales.
Maturity phase with large and nearly constant sales, and.
Decline phase with decreasing sales and eventually withdrawing from themarket.
It is desired to keep the maturity period going as long as possible. However, thePLC gets shorter and shorter due to rapid technological change, global markets andmultiple vendor environments, fierce competition and partnerships or alliancesenvironment and ever-increasing customer expectations.
1.3 Notions of Reliability and Quality
1.3.1 Product Reliability
Reliability of a product or system conveys information about the absence offailures, and is usually defined as the probability that the system will perform itsintended function for a specified time period when operating under normal orstated environmental conditions e.g., see Ref. [41. This definition deals with thefollowing four important points:.
Intended function. It actually defines what the failure is. Failure can be a total loss of function termed as hard failure or a part loss of performance when the performance degrades to a specified level termed as function failure or softfailure Uncertainty or randomness of time to failure. It is reflected by the word"probability." The uncertainty is due to many factors, including the variability in raw materials, manufacturing, operating, and environmental conditions.
Planning horizon or mission duration. It is reflected by the phrase "specified time period." .
Use environment. It is reflected by the phrase *"normal or stated environmental conditions." Product design and reliability assessment are based on a set of nominal conditions such as usage intensity or load profile a graph of load versus time, operating environment, and maintenance activities. These conditions determine stresses on the components and affect degradation rate. If these conditions or activities are different from the nominal, the reliability performance in field will be different from those assessed in or derived from the nominal conditions.
The reliability of a product is mainly determined by the decisions made duringthe design and development and in the manufacturing of the product, and dependson a number of factors, including manufacturing quality, operating environmente.g., heat, humidity, dust and chemical solvents, usage intensity frequency andseverity, maintenance activities e.g., frequency and depth of preventive mainte-nance, and operator''s skills e.g., see Ref. [31.
The product reliability is important to both manufacturer and consumer. For themanufacturer, the conseq
