4) Assessment of Outcome 1: (20 points total) Time standards are being introduced into a plant that has never used them before. The factory operates two shifts (4000 hr/yr) with a total of 200 workers divided evenly between the shifts. The products manufactured are produced in batches. Each batch consists of all of the different styles to be made. The standard time to assemble a product averages 3.68 min. Batch quantities range between several hundred and several thousand, with an average - 1800 products. Assume that one worker is responsible for producing an entire batch. Standards are set by direct time study, with an average application time per study 3.1 hr. All batches are unique (no repeat orders), so a time standard should be set for each batch. However, some batches are produced without using time standards and the factory owner's experience is that the average time to assemble a product without standards is 35% longer than with standards. (a) How many time study analysts are needed to set standards on all of the batches (100% coverage), if each analyst works 2000 hours per year? (b) If the average wage rate of a garment worker is $10/hr with fringe benefits, what are the annual savings in labor cost to the owner by setting standards on all batches? Final Answers: (a)
