ASSIGNMENT

DRIVE	WINTER 2013
PROGRAM	MBADS – (SEM 4/SEM 6) / MBAN2 / MBAFLEX – (SEM 4) / PGDISMN (SEM 2)
SUBJECT CODE & NAME	OM0017 – Advanced Production and Planning Control
BK ID	B1342
CREDITS	4
MARKS	60

Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Q.1 Write short notes on:

(Classification of Inventory Models, Role of Controls in Operation Cycles, Forward scheduling, PPC for Different Systems of Manufacturing) (2.5 marks each)

Ans :  Classification of Inventory Models:

An appropriate inventory model can be selected through the new classification system. The classification of inventory models is based on the salient features of inventory. This system of classification enables practitioners to understand inventory models and choose the best model for a given set of inventory conditions. Various

Q.2 Five jobs are to be processed at a work station. The processing time and the due date in days are given below. Determine:

a) The sequence of job according to the shortest processing time.

b) The total completion time.

c) The mean flow time or average completion time.

d) The average number of jobs in the system each day,

e) The average lateness.

Job                                                    A  B             C             D             E

Processing time in days                6              19           16           11           13

Due date in days                             8               22           20           14           14

Ans : a) The sequence of job according to the shortest processing time.

The sequence ADECB is based on the shortest processing time first.

Job Sequence   Processing Time ( in days)   Total Flow time days      Due days        Late (days)

        A                        6                                            6                                           8                    0

      

        D                      11                                           17 (6+11)                            22                   6

           

        E                      13                                           30 (17+13)                           20                   17

        C                      16                                           46 (30+16)                           14                   30

        B                      19                                           65 (46+19)                           14                  46

       Total                  65                                          164                                                      99

b) The total completion time.

c) The mean flow time or average completion time.

d) The average number of jobs in the system each day,

e) The average lateness.

Q.3 Differentiate between FMS and standalone machines. Describe a few Applications of FMS in Industries

Ans: Differentiation between FMS and standalone machines:

FMS vs. Stand Alone Machine: The main advantage of FMS seems to be their flexibility. In traditional processes/technologies any change to machines need to be carried out on the hardware itself. However, new manufacturing technologies like, FMS hold the commands in the form of software, which can be easily changed. FMS may

Q.4 Write short notes on: Material Requirement Planning, Forecasting in Operations Off shoring Agile manufacturing

Ans:  Material Requirement Planning :

MRP estimates and maintains an optimised manufacturing plan. This plan is based on sales forecasts, inventory status, master production schedules, open orders, and bills of material. If MRP is well executed then the cash flow can be reduced and profitability increased. MRP will enable you to be pro-active rather than re-active in the management of your inventory levels and material flow. Material requirements planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, while it is possible to conduct MRP by hand as well.

An MRP system is intended to simultaneously

Q.5 Define quality planning. Explain the phases of quality planning

Ans: Definition of quality planning:

Quality Planning is defined as a “Systematic process that translates the quality policy into measurable objectives and requirements, and lays down a sequence of steps for realising them within a specified timeframe. Quality planning allows quality to be designed into the deliverables of the project before the first task has begun. It is therefore done during the development phase of the project life cycle. It may involve identifying standards or best practices. Design of experiments is one tool that identifies which variables will have the most influence on the final quality of a product

Q.6 Explain the importance of Supply Chain Management(SCM) and the problems addressed by SCM.

Ans: Explanation of importance of SCM:

Organizations increasingly find that they must rely on effective supply chains, or networks, to compete in the global market and networked economy. In Peter Drucker's (1998) new management paradigms, this concept of business relationships extends beyond traditional enterprise boundaries and seeks to organize entire business processes throughout a value chain of multiple companies.

In recent decades, globalization, outsourcing, and information technology have enabled many organizations, such as Dell and Hewlett
