ABSTRACT

One of the tasks of the human operator supervising a complex process plant is to respond appropriately to disturbance situation. The aim of this paper is to correlate the productivity improvement and the disturbance management. Disturbance management is basically deviation from assumed position whereas the productivity is related with the output from the system. In disturbance management of complex dynamic systems causal reasoning plays an important role. This paper provides some aspects of causal reasoning. It deals with the causal field and focus in causal reasoning. By means of simple examples it is shown how productivity is affected by disturbance management

Disturbance Management, Productivity

INTRODUCTION

At the international level, concern for productivity is principally aimed at establishing competitiveness against the production of different countries in term of quality, technology and cost of production. At the enterprises level, main concern is towards utilization of resources to as to produce optimum result of performance. Nothing stand still in this world, world is fast changing. So companies , for survival in today competitive market, have to produce sufficient goods and services while consuming less resource should be managed properly.

The confined progress of any industry is dependent on its ability to optimally and judiciously allocate and utilize its resources so as to provide desired products and /or services at the right time, place price, quality and quantity to the commodity. This requires an integrated approach, an effort to raise productivity and reduce waste. High levels of productivity result in more quality goods at lower costs, which is the basis for lower prices, higher purchasing power and real earnings improvement in working and living conditions and sometimes even shorter working hours. Disturbances are referred to as ‘abnormal situations’ within the context of the control which can affect the efficiency of the system.

An ‘abnormal situation’ is a general term, that is applied when a process deviate from the acceptable normal range of operation. One of the tasks of human operator supervising a complex process plant is to respond appropriately into disturbance situation. The foremost reason behind companies driving importance to disturbance management because only a high reactive and frictionless order fulfillment and order management; as a result, disturbance management is becoming essential part of process plant.

WHAT IS DISTURBANCE MANAGEMENT

A degree of functional nonfulfillment has a noticeable effect on a planned or defined process, further this is called disturbance. In common there occurrence is possible, but actually there is no chance to forecast the time of occurrence. The task for disturbance management is to provide a structure in which disturbance can be managed controlled, providing an applicable solution according to the situation area and the time of appearance of the disturbance.

The key elements of disturbance management are:

1. Communication: reliability and structure
2. Knowledge: measurability and applicability
3. Technology: exchangeability and application

Need of Disturbance Management

In response to an unfamiliar disturbance situation the operator has to consider several possible strategic response types; Compensate disturbance, Compensate consequences of the disturbance, Shut –Down, Repair.

The choice of a specific strategy should be derived on the basis of an overall assessment of the situation.

Typically such an assessment will have to consider aspects such as: The kind of disturbance, Its possible consequences in relation to overall system goals, The available actions and time resources.

It cannot be assumed that the information needed to carry out proper assessment and therefore result will be more losses due to break down and consequence effect.
