The analysis of personal and delay allowances using work sampling technique in the sewing room of a clothing manufacturer

Abstract

PurposeThe aim of this paper is to study the operator activities in garment industry and the percentages of distribution of operations and to analyze the personal and delay allowances by observing the operations and deriving the ratios within a manufacturing period.Design/methodology/approachA work sampling technique is used. Relevant reports (1978‐2004) are studied to give the basis and methodology of the technique. In accordiance with work sampling techique, the operations to be observed in a sewing room are defined, the number of observations and observers required for each day and the procedure for making observations are determined and the distributions of work flows are calculated.FindingsIt is found that 72.7 per cent of working time in an general sewing room was spent for productive activities and 23.2 per cent for personal and unavoidable delay allowances.Practical implicationsWork sampling technique gives information about personal and delay allowances in a work flow of any sewing room. When the distributions of activites are determined, it is possible to find which activities are most responsible for low efficiency. For this purpose, standard operations time in a sewing room should be determined by time measurement studies and work flow should be organized.Originality/valueThis paper deals with an actual sewing room and gives general information about the distributions of activites in work flow which should be used for organization of any sewing room.

An intelligent system for production resources planning in Hong Kong garment industry

“…One possible reason for the lack of investigations could be due to the high complexity of the industry. According to [14], the garment manufacturing industry is more complicated than many other industries as it consists of various machines, labors and thousands of bundles of cutting pieces producing different styles simultaneously. Conventionally, in the garment industry, there is a lack of standardized approaches in resources management where human judgments are used to determine resources planning decisions.…”

Determination of Allowance Time by Work Sampling and Heart Rate in Manufacturing Plant in Juárez México

“…It is performed in those activities that do not have a work method and very consuming time activities and could be more than one monitored resource. This technique has been used to measure productivity in the construction area [2], automotive industry [3], brewing manufacture [5], and clothing industry [6], but it can actually be used to measure the efficiency of any company.…”

“…Personal and delay allowances are very important for every industry [6]. Having an incorrect standard time directly affects productivity, operators, and quality, among other metrics in the company.…”

Identifying Wastages and Calculating SMV through Work Sampling Study in Sewing Section

“…They are allowed to take up to 15% time for relaxation and machine attention as allowances [8] .But beyond the allowances, the sewers wasted their time in involvement with some non-value added activities such as gossiping to the other workers, reworking, waiting for work, being idle intentionally. In sewing section it is found that garment workers spent 72.7% time in productive activities and the 23.2%time in personal allowances and unavoidable delay [9]. Another study revealed that the sewing operators engaged in 40% time in main operation 33.25% time in associated operation and rest of 26.7% in allowances [10].…”

“…The work sampling studies [9] & [10] are conducted in the sewing floor to identify delay and other allowances to but not to measure SMV of the sewing process. Work sampling study result will help the management to visualize the sewing floor and to take right initiative to minimize the wastage through proper supervision and line balancing.…”
