Work system design

  1. 1.  Cost Structure 1.Washing and Ironing = Rs 10 per cloth, Heavier Bedspread 12Rs. 2. Only Ironing = Rs 3 per cloth 3. Operating in a 10*10 room ( Collection, Ironing & Delivery) 4.Types of clothes processed: All type 5.No of Employees = 5
  2. 2. Item Type number of items Shirts 150 Pants 70 Shorts 30 T-Shirts 60 Jeans 40 Salwar 5-10 Bed Spread 3-5
  3. 3.  Every day after 10 (closing time) they will sort out and segregate the clothes depending on the colour(white and other light colour separation)  Next morning clothes are taken to dhobi ghat to be washed. (no special treatment except mentioned segregation). number of workers=2.  1 worker collects(or delivers) clothes from MDP and faculty quarters before 9 am in morning.  Rest 2 workers stay at their workplace to deliver the clothes to the students who come to collect it.
  4. 4.  After washing the clothes at Ghat, one of the workers returns while one remains there at ghat until all the clothes are dried. Sometimes they use drier to fasten the procedure.  At around 3 pm, 2 workers start ironing the clothes while 2 workers are responsible for delivering the clothes to faculties and MDP.  One worker is dedicated to deliver the clothes to the students who come to collect them.  At night, they segregate the clothes again according to the customers. This procedure has a lead time of 2 days during normal days(normal temperature and humidity)
  5. 5. Collection of clothes  Instead of the students carrying the clothes to the laundry facility, the workers will come to collect the clothes at the hostels everyday.  Timing : - Arrival : 9 am - Waiting Time : 1 hour  Average clothes collected in one visit = 1000 ( For all the three hostels)  Venue for collection of clothes : New Hostel Basement  No of workers involved in collection of clothes = 3  Each worker will carry one trolley with him to collect the clothes
  6. 6.  Transportation of clothes from hostel to laundry facility as well as from facility back to hostels will be done with the help of cycle trolleys  No of trolleys : 3  The capacity of the 3 trolleys will be different according to the hostel strength.  The trolley for hostel 5 will be largest in size and the one for hostel 2 will have least capacity
  7. 7.  System for tagging used will be the existing one itself  The learning curve for the existing technique is quite high  The workers take very less time to perform that task  Efficient technique as the mark does not get washed away  Tagging will be done on one of the cloth which will be used to tie the others together for a particular customer (student)  Tagging on the other clothes will be done at the laundry facility  During the transportation back to the hostels, stacking of the clothes with similar tags will be done and the stacks will be arranged according to the hostel floors
  8. 8.  The clothes collected from different hostels will be aggregated at Dhobi’s work place in college and labelling is done  Now these aggregated clothes should be segregated depending on the category (shirt, jeans etc.,)  As the aggregated quantity is high, transporting this load of clothes to the Ghat is a challenge. We may be required to use an auto-rickshaw to do the ferrying  The schedule of the auto-rickshaw would be as follows:
  9. 9. Monday Tuesday Wednesday Thursday Friday Saturday Sunday Pick’s up segregated clothes to Dhobi Ghats in the morning Pick’s up segregated clothes to Dhobi Ghats Delivers segregated clothes from Dhobi Ghats in the evening Delivers segregated clothes from Dhobi Ghats in the evening
  10. 10. • Washing and drying are continued •All clothes are delivered to workplace at college by evening • Clothes are again segregated based on tag and Ironing commences Sunday • Continues to iron the clothes, stacks them into trolley and brings them to respective collection points by evening • Delivers the ironed clothes and collects the clothes that need to be washed and tags them at the collection point • Brings and aggregates all clothes to the workplace in college and segregate them Monday • Segregated clothes are transported to dhobi Ghat using an auto-rickshaw • Washing commences and drying is done Tuesday
  11. 11. • Washing and drying are continued •All clothes are delivered to workplace at college by evening • Clothes are again segregated based on tag and Ironing commences Wednesday • Continues to iron the clothes, stacks them into trolley and brings them to respective collection points by evening • Delivers the ironed clothes and collects the clothes that need to be washed and tags them at the collection point • Brings and aggregates all clothes to the workplace in college and segregate them Thursday • Segregated clothes are transported to dhobi Ghat using an auto-rickshaw • Washing commences and drying is done Friday • Washing and drying are continued •Workers may take some rest Saturday
  12. 12.  The workplace at college is cramped, but since the new model doesn’t require unwashed clothes (they are collected and sent directly to ghat very next day) to be stocked up the work place can be well utilized  The work place is hot and humid so installing an exhaust fan may help the worker to work with ease
  13. 13. An Ergonomic Study of Muscular Fatigue during Ironing Clothes Present Situation: Board Height: 82 cm Weight of Iron: 2.92 kg (Heavy Type) Avg. No. of clothes Ironed per day : 265 No. of workers to be studied: 2 (Men) {weighing 75kg each with avg. height of 5’10”} Cost of Ironing: Rs. 3.00 per cloth  Due to use of heavy weight iron the workers were suffering more fatigue and muscular strain. The movement of iron over the cloth was not standardised according to the type of the cloth. Iron temperature was controlled using bundle of clothes tied together to absorb extra heat. Heat control was necessary as the material of few clothes could not be recognised easily i.e. whether 100% cotton or Polyester cotton blend. This setting of temperature was adding inefficiency to the ironing process and was based on experience, failing to which can cause burning of the cloth. Electric switch was mounted far away from the table, forcing them to use long iron wires which obstruct operator during ironing.
  14. 14. Suggested Improvements For Increased Efficiency  Operators were encouraged to use light weight (0.77 kg) or steam iron (1.29 kg) to reduce muscular strain and fatigue. Lead time to iron a cloth was reduced by 60% by the use of light weight iron and 50% by the use of steam iron as the movement of iron base plate was easy over the cloth. Switch board was mounted near the ironing board and the wire length was reduced by 1/3rd of the previously used wire. They were suggested to have training of reading garment labels in order to recognise the type of ironing and temperature suitable for ironing that garment. The ironing was suggested to be done in two batches with proper time interval in order to reduce fatigue. Estimated improvement in time and cost will be 2 Rs
