(Q&A)
Q: 1. What is Enterprise Resource Planning (ERP) ?
A:1. ERP is an integrated suit of application software modules providing operational,managerial and srategic information for improving productivity,quality and competitiveness.
ERP system optimise the 4 m's-men,machines,materials and money.
Q.2. What is Global Positioning System (GPS) ?What are it's limitations ?
A. GPS is a satellite based tracking system used to determine the position(latitude,longitude &altitude) ,velocity&time using GPS receivers and radio signals broadcasted from GPS satellites.It has 3 parts-namely space segment,user segment and control segment.
The limitations of GPS are followings...a. Availability of satellites b. satellite geometry c. multipath
d. configuration of area of interest e. atmospheric effects.
Q:3. What is systematic approach in production management ?
A. Systematic approach in production management consists of 5 steps-i. Selection of the operation for imrovement ii. Collecting facts by breaking down the operation into detailed steps. iii. Analyze the facts by a system of questionnaires iv. Formulation of new method v. Develop and install new method
