... The correct development of Maintenance 4.0 relates to the correct implementation of Industry 4.0. Practical implications Maintenance 4.0 will greatly improve the main operating indicators: safety, reliability, availability and cost. Social implications Maintenance 4.0 will contribute to a circular...

... in order to maximise the overall system reliability, while a penalty function modelling cost of reliability improvement is minimised. The resultant continuous and nonlinear optimisation problem is scalarised by a convex combination of the criteria and the MATLAB Optimisation Toolbox is used to generate...

.../approach First, the current “risk priority number” (RPN) being used within the FMEA is developed. Second, a case study is conducted in cooperation with an automotive supplier in order to test the applicability and benefits of the new approach. Findings By implementing the cost‐oriented FMEA, quality...

... organisational motivation, possible application, costs and benefits, critical success factors and the central importance of prerequisite statistical thinking (ST). Design/methodology/approach A three stage, mixed methods approach was adopted, incorporating surveys augmented by case studies and key informant...

...Johannes Freiesleben Purpose The objective of this paper is to demonstrate basic economic principles underlying the use of inspection systems and to derive a basis for comparing inspection costs with the alternative costs of quality improvement. Design/methodology/approach For this purpose...

...Stefanka Chukova; Yu Hayawaka; Tadashi Dohi; Yu‐Hung Chien Purpose To investigate the optimal burn‐in time from the perspective of minimizing the expected total cost (i.e. manufacturing plus warranty costs) per unit of product sold under a failure‐free renewing warranty policy. The conditions...

..., the operational profile of the software is modeled, and the total expected software cost incurred in both testing and operational phases is formulated. Findings Under a milder condition, the optimal warranty period which minimizes the total software cost is derived analytically. Originality/value...

...Fábio Luís Ramos da Silva; Katia Lucchesi Cavalca; Franco Giuseppe Dedini The aim of both value analysis (VA) and quality function deployment (QFD) is to reduce waste by avoiding redesign and providing optimal location of costs in general. To satisfy the consumer's most important needs, the VA...

...M. Ben‐Daya; S.O. Duffuaa In this paper we incorporate Taguchi's loss function in the economic design of the control chart. This is done by redefining the in‐control and out‐of‐control costs using Taguchi's loss function. The new model brings Taguchi's off‐line concepts to the classical SPC...

...Surajit Pal; G.S.R. Murthy In this article we present an application of Gumbel's bivariate exponential distribution model in the context of estimating warranty costs of motor cycles under a new warranty policy. The problem in question is as follows: Under the present two‐dimensional warranty policy...

... by quality of service, cost/value of the meal, and place/ambience of the restaurant. Bell (1993) reported that restaurateurs are always searching for strategies to market to the post‐baby‐boomers. According to Siudzinski (2001), the profile of employees has to be appropriate to the age of customers...

...Frank Beichelt The purpose of this paper is to propose, motivate and discuss a policy for optimal scheduling replacement intervals of technical systems only on the basis of maintenance cost parameter: a system is replaced by a new one as soon as the maintenance cost within a replacement cycle...

... as being key to improving product quality, production output, costs and shareholder return. Focuses on the project initiated to research, develop and implement the most advanced maintenance practices and information technologies to achieve maximum equipment reliability. Reports on the successful outcomes...

...Hareton K.N. Leung; Keith C.C. Chan; T.Y. Lee This paper presents the result of a study to identify the costs and benefits of obtaining ISO 9000 certification. Toward this goal, a survey of some 500 ISO 9000 certified companies has been carried out. Among them, more than 65 per cent believe...

...Marco Perona Taguchi’s quality loss function is here proposed as a tool to evaluate costs connected to non conformity in manufacturing industries. First of all, Taguchi’s quadratic cost function is compared with the traditionally adopted zero defects cost function, and the differential effects...

...Sui Pheng Low; Henson K. C. Yeo There are three components that make up quality costs: prevention, appraisal and failure costs. The ISO 9000 standard introduces a quality management system that has been widely claimed would reduce the costs of business. One of the ways it does this is through...

... must review and document their management procedures, prepare a quality manual and have their processes periodically assessed by an approved external body. The broad research question guiding this study was: “Does ISO 9000 work, and if so with what benefits and costs?’’ A large number...

...Won Young Yun Considers the estimation problem of the total warranty cost under two types of warranty. The product (e.g. car) is sold under two types of warranty (mileage and age). The failed product will be minimally repaired by the manufacturer during the preassigned warranty, the length of which...

...Mark D. Hanna; J. Marcus Jobe © Emerald Group Publishing Limited 1996 Acceptance sampling Costs Economic order quantities Lot size In recent years, acceptance sampling has been downplayed as a recommended tool because of the implication that quality is inspected...

...T.F. Burgess Existing quality‐cost models have been criticized for their imprecision and inadequate theoretical justification. Attempts to remedy these deficiencies by using systems dynamics to build a generic model relating quality conformance levels to the quality‐cost categories of prevention...
