Question
Chapter 17, Problem 1DQ
Summary Introduction
To determine: The objective of maintenance and reliability.
Introduction: Reliability is the probability that a product can perform over a specific period. It is the consistency of the product to perform in the same way for a particular period of time.
Expert Solution & Answer
Explanation of Solution
The objective of maintenance and reliability is as follows:
The major objective of maintenance and reliability is maintaining the ability or competency of certain system in the meantime while controlling the cost of the system.

- QUESTION 6 (MAINTENANCE AND RELIABILITY: COMPARING PREVENTIVE AND BREAKDOWN MAINTENANCE COSTS) 17.24 Wharton Manufacturing Company operates its 23 large and expensive grinding and lathe machines from 7 A.M. to 11 P.M., 7 days a week. For the past year, the firm has been under contract with Simkin and Sons for daily preventive maintenance (lubrication, cleaning, inspection, and so on). Simkin's crew works between 11 P.M. and 2 A.M. so as not to interfere with the daily manufacturing crew. Simkin charges $645 per week for this service. Since signing the maintenance contract, Wharton Manufacturing has noted an average of only three breakdowns per week. When a grinding or lathe machine does break down during a working shift, it costs Wharton about $250 in lost production and repair costs. After reviewing past breakdown records (for the period before signing a preventive maintenance contract with Simkin and Sons), Wharton's production manager was able to summarize the following patterns: 1…arrow_forwardQUESTION 15 Tradeoff analysis on different design concepts are performed and the data obtained are shown in Table Q15.1. The manufacturing cost of the design concept has been estimated and the reliability score of each design concepts has been ranked on a scale of 1-5. In both cases, low scores are considered good. The customer has agreed weighting factors of 55% for reliability and 45% for manufacturing cost.

This method focusses on producing and delivering goods only when they are needed, which helps streamline operations and improve efficiency. Originating from manufacturing practices, JIT aims to eliminate the seven types of waste, thereby optimising resource use and enhancing productivity. For this task, choose the same Malaysian-based manufacturing company as in Question 1 and create a comprehensive report detailing its adoption and implementation of the Just- in-Time (JIT) methodology. The report should explore how the company has applied JIT principles to reduce waste, improve operational efficiency, and maintain a lean inventory system.
