Concept of Industrial Engineering (IE):
Industrial Engineering (IE) is concerned with the design, Improvement, and installation of integrated system of men, material, and machines for the benefit of mankind. It draws upon specialized knowledge and skills in the mathematical and physical sciences together with the principles and methods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems. Now industrial engineering is an integral part of garment manufacturing. It is treated one of the important element in the apparel industry to improve productivity and secure requested delivery date. By applying IE tools and techniques, engineers can enhance the production floor performance. In garment factories, this usually means reducing bottlenecks, setting standard times, balancing sewing lines, and controlling material flow from cutting to finishing. In this article I will discuss on different tools and techniques of industrial engineering those are applied in apparel industry.
Tools of Industrial Engineering:
The main aim of tools are to improve the productivity of the organization by optimum utilization of organizations resources: men, materials, and machines. The major tools used in industrial engineering are:
- Production planning and control.
- Inventory control.
- Job evaluation.
- Facilitates planning and material handling.
- System analysis.
- Linear programming.
- Simulation.
- Network analysis (PERT, CPM).
- Queuing models.
- Assignment.
- Sequencing and transportation models.
- Games theory and dynamic programming.
- Group technology.
- Statistical techniques.
- Quality control.
- Decision making theory.
- Replacement models.
- Assembly line balancing.
- MRP, JIT, ISO, TQM etc.
In apparel manufacturing, these tools are usually used together rather than in isolation, and the first ones most factories apply are production planning, work measurement, line balancing, and inventory control because they directly affect output and delivery.
Techniques of Industrial Engineering:
Planning and designing manufacturing processes and equipment is a main aspect of being an industrial technologist. An Industrial Engineer is often responsible for implementing certain designs and processes. Industrial Technology involves the management, operation, and maintenance of complex operation systems. Techniques of industrial engineering are-
1. Method study:
To establish a standard method of performing a job or an operation after thorough analysis of the jobs and to establish the layout of production facilities to have a uniform flow of material without back tracking. In an apparel line, this can include changing the order of operations, reducing walking distance, and placing machines or trims to avoid backtracking.
2. Time study (work measurement):
This is a technique used to establish a standard time for a job or for an operation. In garment factories, the result is often used to set operator targets, calculate line capacity, and compare actual output with planned output.
3. Motion economy:
This is used to analyses the motions employed by the operators do the work. The principles of motion economy and motion analysis are very useful in mass production or for short cycle repetitive jobs. A common example is arranging bundles, tools, and attachments within easy reach so operators do not waste time on unnecessary hand movements.
4. Value analysis:
It ensures that no unnecessary costs are built into the product and it tries to provide the required functions at the minimum cost. Hence, helps to enhance the worth of the product. In apparel, this may mean reviewing fabric consumption, trims, packing, or stitching methods to remove cost without lowering quality.
5. Financial and non-financial Incentives:
These helps to evolve at a rational compensation for the efforts of the workers. In practice, this can include piece-rate bonuses, attendance rewards, skill-based pay, or recognition for maintaining quality and efficiency.
6. Production, planning and control:
This includes the planning for the resources (like men, materials and machine) proper scheduling and controlling production activities to ensure the right quantity, quality of product at predetermined time and pre-established cost. For garment orders, this is the point where buyer delivery dates, line loading, raw material availability, and finishing capacity have to be matched carefully.
7. Inventory control:
To find the economic lot size and the reorder levels for the items so that the item should be made available to the production at the right time and quantity to avoid stock out situation and with minimum capital lock-up. This is especially important for fabrics, accessories, and trims, because even a short shortage can stop the whole production line.
8. Job evaluation:
This is a technique which is used to determine the relative worth of jobs of the organization to aid in matching jobs and personnel and to arrive at sound wage policy. It also helps the factory compare operator, checker, and supervisor roles more fairly when setting wages and responsibilities.
9. Material handling analysis:
To scientifically analysis the movement of materials through various departments to eliminate unnecessary movement to enhance the efficiency of material handling. In garment units, this often focuses on bundle movement, trolley routes, storage location, and the distance between cutting, sewing, finishing, and packing.
10. Ergonomics (Human engineering):
It is concerned with study of relationship between man and his working conditions to minimize mental and physical stress. It is concerned with man-machine system. Good ergonomics in apparel factories can reduce fatigue, improve accuracy, and lower injury risk by adjusting seat height, table level, lighting, and machine reach.
In garment factory, these techniques are most effective when they are linked to daily line data, operator performance, and style changes, because production problems often start with poor method design or unrealistic targets.
Conclusion:
Industrial engineering becomes most useful in garments when the factory applies its tools regularly, not only when problems appear. Small improvements in method, time, flow, and planning can create a steady gain in output and delivery performance.
