Figure-1: Scope of production control system
Activities of Production Planning and Control (PPC) System in Garment Industry:
Major concepts or activities of production making plans and control system are discussed below.
1. Demand forecasting:
Starting point of the PPC sport.
Future demand for products/service is the least bit times uncertain; so wishes to be predicted.
Forecasting horizon (i.e. interval covered by forecast) depends on the nature of the product and the lead time between the time an order is positioned to shop for raw fabrics and the time these fabrics are transformed and shipped out as finished goods. It may be days, weeks or months.
Without a rather precise forecast of long time period demand, it is most unlikely to accomplish the long-rate skill making plans sport.
2. Capacity making plans:
Second step in PPC sport
Done in two procedures- long stove and brief stove.
The need is to comprehend:
i. How many persons to employ?
ii. How tons further time to schedule?
iii. How tons stock to preserve?
The target is to meet the exact demand economically.
If insufficient skill or stock exists, demand cannot be met and shoppers may be misplaced. If too tons skill and stock exist, the undertaking shall be in a serious payments circulate bind.
If incorrect products are in the pipe line, the undertaking shall be hurt at both ends-hiring unhappy shoppers and unusable products.
Reasonably precise demand forecasting is an vital pre-requisite to skill making plans.
three. Inventory monitoring and control:
One difficulty of skill making plans is the quantity of stock to be held.
A unheard of plan whereas there's a cyclic demand is to construct more than what's needed throughout slow durations, thereby rising stock. Thus, whereas the demand is high, it may be met in earlier sort inventoried models. Therefore, stock ranges will vary sort interval to interval. With these versions in stock, production quantity on each order will also vary.
The control of stock is the act of comparing what's in particular handy with the specified quantity.
4. Short stove standards making plans:
Second sport that feeds off of the skill making plans output. This sport also responds to the selections of stock control.
The sport is one in all mean-time period production skill and aims, existing stock ranges, and discrepancies between these ranges and wished stock, then creating a master schedule of what to do in each production branch throughout a better week or month.
To some extent, inaccuracies in the forecasted demand and alterations in the skill plan may be overcome at this stage. The amount of further time and below skill may be adjusted. Thus there's a degree of suppleness inside the broader limits of the skill plan.
The resulting output is the brief-stove standards plan or master schedule.
5. Shop scheduling:
The master schedule is made regardless of the dynamic alterations in the shop situation.
i. Schedule ought to be changed:
If persons fail to arrive at work. Or
If a machine collapses or breaks down.
ii. Schedule ought to be adjusted:
If scrap formulation are discovered. Or
If tooling is quickly unavailable.
The master schedule then identifies the weekly production aims for every branch yet does not exercise session how these aims are to be met. This is the role of shop scheduling sport.
At the foundation of each shift, the shop foreman should review what's required relative to the master schedule and what resources are obtainable to him. He should make a choice what to do throughout the shift, the sequence wherein shop orders ought to be accomplished and the resources to devote to these initiatives.
These production control selections are them handed on to the production employer.
6. Dispatching and expediting:
Dispatching consists of the free up of priceless work orders, time tickets and so forth. to authorize timely get started of operations and to report get started and conclude time of each job.
Expediting is logical step after dispatching which coordinates the progress operate appreciably to execute the production plan successfully. Here, monitoring is done by the controller to check whether or not the production rate is consistent with the production schedule.
Thus, the production control sport is a series of interrelated occasions that concepts as a system. The selections are made for a type of horizons in time and with other degrees of accuracy to adequately make the most of the constrained resources.
