This project work has been divided into five chapters. Chapter one deals with the introduction of the approach, the statement of problems, research questions, objective of the study scope of the study and significance of the study, chapter two is review of related literature both on computer and inventory planning and control in an organization.

CHAPTER ONE

INTRODUCTION

• Background of the study

The As there are different scholars in computer science, so are there different definitions of computer. The same is applicable to inventory planning and control, however all boils down to the same meaning at least though from different perspectives depending on the understanding.
Iyang (1996:40 defined computer as” an electronic data processing machine capable of receiving, storing, performing arithmetic and logical operations in line with defined instruction, high speed, accuracy and finally transforming the processed data to an output or presenting the data or information in a final printed or visual from”. A computer system could as an “Electro- mechanical machine which receives data instructions, processes them and produce its result as information which are made up of hardware, software, data ware, and human-ware, computer technology is fast revolutionizing the world, Before computer there had been aids to doing such actions as calculation, storing and retrieving information, which were adopted by various organizations.
In the same view, Arnold (1996:221) defined inventory as materials and supplies that a business or institution carries either for sale or to provide inputs or supplies to the production process. All businesses and institutions require inventories which forms the life wire of any organization. Similarly, inventory planning and control for. According to Arnold (1996:223) is responsible for managing and directing inventory from the raw material stage to the customer. Inventory planning and control involves a wide rage of activities like planning, purchasing, storage, usage and control of inventory and for this to be effective, come the use of computer inventory for easy accessibility.
The role computer play in inventory control be over- emphasized. The computer assemblies all pertinent facts about inventory planning and control and bring all these facts up to date. This has been made possible, by the fact that inventory planning and control recognizes that important role computer plays in inventory. Successful inventory planning and control actions are as a result of a computerized inventory system, where all the additions and withdrawals are recorded electronically, so that the computer can trigger the placement of orders to replenish the inventory. Since inventory is necessary for any company dealing with physical products, what it handles large volume of inventory can best be imagined when told like a storey and it beats human imagination when put into use and it is proved.
Brief history of Sam Mbakwe international cargo airport (SMICA). The airport was built but the Administration of late chief Sam Mbakwe. First Civilian Governor of the old Imo State made up of the present Imo, Abia and part of Ebony State. The airport was renamed after late chief Sam Mbakwe as an honour for his contribution to growth of the country and aviation industry Sam Mbakwe international cargo Airport, Owerri was officially commissioned on the 15th July 1994 by the former head of state commander. In- chief of the Armed forces, Federal republic of Nigeria, Late general Sanm Abacha as a passenger airport, recently, it has been re-designated a cargo airport for the importation of cargo in the eastern geo-political Zones of the country by the former president and commander in- chief of the armed forces of the federal Republic of Nigeria, chief Olusegu Obasanjo.
The Airport is managed by one federal Parastatal and three Agencies namely, Federal Airport Authority of Nigeria (FAAN), Nigeria airspace management Agency (NCAA) and Nigeria meteorological service Agency (NIMET) . The Airport has as purchasing and stores department where materials of different kinds are purchased and kept for services and which as highly monitored by computer so as to maintain efficient and effective inventory planning and control, it is located at Ngorokpala L.G.A

1.2 STATEMENT OF THE PROBLEM

The problem of inventory planning and control has been very daring but it has also been within the past years that this scientific method in computer was introduced in various companies and establishments to promote proper inventory planning and control. The researcher desired to go into the major problems which the establishment have been experiencing before the use of computer was imitated and deduced remedies and solutions in solving these problems. As a result of many operational activities of industries and establishments, they have found the difficult with the surge in business activities. The function of the stores is changing into a more complex one, which emphasized the availability of information at the shortest possible and also the speeding up of time used in rendering certain services. This means that, the use of manual operations could not effectively handle the whole work load and this almost led to a less servicing activities to different operational areas. This also means that materials shortage were delays in stock recording and delivery, at times a complete halt as shortage of material will hit the services operations. Computerization is then seen as answer to those problems facing servicing and manufacturing industries that operates a large system and has the finance and manpower quickly embraced the new technology.
Beside the role of computer in inventory managements face a lot of difficulties due to the following problems.
(a) Inability to determine correctly the exact period of replenishment stock and the economic order quantity.

(b) Inadequate planning and effective control of stock.
(c) Unfavorable internal and external factors which influences inventory planning and control

(d) Inability of the inventory managers to predict with certainty into the future of their customer demand.

(e) Shortage of funds available to business managers and the need to resolve the liquidity and profitability conflict.

(f) Poor accounting documentation of stock
(g) Lack of unskilled personnel to operate the computer system.
(h) Hum Sum of money involved in the purchase of computer system.
(i) Unauthorized persons getting access to the computer system.
(j) The difficulty of correcting errors when they occurs, when the wrong code number is entered the various services rendered in inventory planning and control and how this application has affected output and efficiency.

1.3 OBJECTIVE OF THE STUDY

Whatever be the nature and structure of a country for instance Nigeria, Sam Mbakwe International cargo airport has contributed immensely to the success and development of the country hence international buying and selling via relationship is concern. To this end the objectives of the study are.
(1) To examine the methods and importance of computer application in inventory planning and control

(2) To identify the effects of computer application in inventory planning and control.

(3) To investigate into the uses to increases the efficiency of the store.
(4) To examine the Overview of computer application to the various services rendered in inventory planning and control.
(5) To identify the desirability and effects of computer application in the storage system.

(6) To find how computer application in inventory planning and control will help change the whole concept of inventory.

1.4 RESEARCH QUESTION

One important thing a research of this nature needs to achieve is to empirically prove the subject matter of the study. This is an order to give direction to readers, other researchers and planners so as to elicit what the research is all about. It is therefore becomes necessary to formulate research questions on which the conclusion would be based and are followed.
a. What things can a computer do in inventory planning and control in an organization
b. Why should inventory planning and control in an organization be computerized.
c. Does computer really increase effectiveness and efficient in inventory planning and control in an organization.

1. How should the computer system be operated in inventory planning and control in an organization
2. Does computerization help in reducing the burden of work in your stores?
   The above research questions are such which reasonable answers can be elicited at the end of the project.

1.5 STATEMENT OF HYPOTHESIS
