1. SCOOTERS INDIA LIMITED SUMMER INTERNSHIP PROJECT ONJOB ALLOCATION AND JOB SHOP SCHEDULING UNDER THE GUIDANCE PROF. RAJESH SHARMA SANDEEP SINGH DY. MANAGER

2. Fundamental optimization technique and having maximum weight in bipartite graph Same number of agents and tasks Each agent incur some cost Assignment total cost of assignment is minimized. Method Hungarian 3. Old company- operation are carry out in old fashion Already invested large amount to convert it into cellular manufacturing. Competitive market 4. OBSERVATIONSTotal no. of machine 40 Total no. Worker 34 (excluding managers) Not working machine 5 Material handling person 1 Randomly person are allocated in a machine (only some person are fixed at their define machine) 5. Poor handling system (picking and set down) No of component 27 No performance analysis Self quality maintain system No define path for material handling process In a general shift not more than 20 machine are running at a time Total no. of person in a general shift are 22 to 24. 6. DATA COLLECTION We take no. Of person with their service no. We find the expert areas of the person ( verbally) Machine detail operation Machine overloading Flow process of given component We take reading of person machine (aprox 250) processing min. 7. Correction in the data by averaging and some manipulation format sampleSERVICE NO. MACHINE NO.COMPONEN T NO.NO. OF COMPONENTTIME TAKEN 8. 1.

Takeless total span of time. Method-simple mathematics 19. First we study the process of each component passes through machine Draw the layout Here we try to find the shortest path if possible by applying shortest path method. Factors we used here Total dimension of the machine: for placement of machines we need perfect space to install the machine. Cycle time of next machine: cycle time of next machine should be such that there will be less waiting time for components which to be processed. Maintenance: surrounding space area and position of machine should be such that there will not be any problem with maintenance. Storage area and movement of raw material: should have required space area for storage. Working condition for the worker. Total cost: should be less as possible. 20. Totaldistance traveled without job shop scheduling is 98230 cm and with job shop scheduling is 90330. Average speed of moving =5.3 km/hr Time taken to make component with job scheduling is 10.22 min and without is 11.12 21. Time taken in a year in min.
