The model fit in the present study was considered acceptable if at least two of the following three criteria were met: a root mean square error of approximation (RMSEA) values < 0.08, P>0.05, and relative chi-square ( ) < 3 (37, 38). In addition, the following goodness-of-fit indices were also used to assess the model fit: Normed Fit Index (NFI; >.90 acceptable), the Comparative Fit Index (CFI; >.90 acceptable), Incremental Fit Index (IFI; > .90 acceptable), Goodness of Fit Index (GFI; >.90 acceptable) (39, 40), and Standardized Root Mean Square Residual (SRMR; < .08 acceptable) (41). An RMSEA value ≥ 1 was considered as model misfit
2.2. THEORETICAL FRAMEWORK This study will be a reflection of theories which support fleet replacements in parastatals. These include Motor Vehicle Replacement Theory which according to Bartlett (1998) states that it determines what age units should be considered for replacement ideally before costs rise, before reliability or safety is reduced and before major capital expenditure is incurred. Coetzee (1994) says Replacement Theory in Operations Research is used in the decision making process of replacing a used equipment with a substitute, mostly, a new equipment of better usage. The replacement might be necessary due to the deteriorating property or failure or breakdown of particular equipment.
In the end ,we discuss about the history of CNC machining and then we compare the advantages and disadvantages of CNC machining against manual operations TABLE OF CONTENTS Content Page Abstract 2 Table of Contents 2 Introduction 3 Experimental Setup and Procedure 4 Discussion 10 References 8 INTRODUCTION The experiment which was conducted at the Mechanical lab was based on two categories , 1. Manual operated machines 2. CNC Machining . In the manual operation part, we manually measure and mark a point on a steel bar using vernier calliper and height gauge. Then we punch the marked
To know the needs regarding information- An analytical study of that information is made which are needed for the external parties related to the organizations. 2. To explain the objectives of MIS- It means to clearly define the objectives in terms of what one will do with the information received by him/her. 3. To determine the sources of information- There are several sources of information and they are internal and external.
Then, a typical risk-based maintenance framework is applied to each risk. The framework is shown in Fig.1 For each identified risk, data needs to be collected. This includes information about the risk, its general consequences and the general methods used to ease and predict the
Setting the objectives must be done before management can identify potential events affecting their achievement. • Event Identification – management identifies potential events that could affect the entity either adversely or presents an opportunity and emanates from internal and external sources. • Risk Assessment – consideration of the extent to which potential events have an impact on the achievement of the organizations objectives. Evaluate the risks that have been identified in order to form a basis for determining their management. • Risk Response – after the determination of relevant risk, management determines how it will respond.

A Q-methodology is used to discover different factors which affect the success of GSD projects. Based on this methodology, factors are ranked by practitioners through survey and results are presented based on these ranking to show different challenges arise in the form of geographical, temporal and socio-cultural differences. To determine GSD project outcome an assessment framework is proposed which evaluate the criteria of different knowledge, software technology, and development team and organization factors. For the assessment of framework a “fuzzy decision making and evaluator laboratory”(DEMATEL) and “fuzzy multi-criteria decision making” (FMCDM) approaches are integrated to determine priority weight of each factors in order to evaluate the outcome of GSD
This is all a part of variation shows by the machines but to know the capability or behaviour of machine and to know whether the process is good, bad, poor or excellent certain capability indices are required that is Cmk, Cpk, and performance index Ppk . Too know the behaviour of machine each job after manufactured is to be check. When a point on chart lands outside the control limits, or when certain anomalous behaviours are observed, the operators are alerted to investigate or perform other actions, it will convenient to imagine the output as representing measurements of quality in manufacturing . The machine capability study concentrates exclusively the characteristics of the machine i.e to extent possible, the influence or effects of variables external to the machine (noise
