A Study of Production Factors Affecting Total Productivity of 'Iran Wood and Paper Industries(Chuka) with Emphasis on Pulp and Paper Production line

Economic progress and ,development of a -country. depends to a large extent on the appropriate
operation of its different industries. Pulp arid paper industry producing a product with high added
value has an important role in this development. Different ways are available for operation
evaluation of a productive unit. One is the assessment of productivity which refers to the way the
' production' ,factors are used to make output. 'This ' study was performed in Iran Wood and Paper Industry (Chuca) which is one of the , largest paper factories with a capacity of 150000 tons of paper , per year. The index approach was used for the assessment of productivities and the study covered a period often years from 1991 to 2000. Different economic as well as physical productivity factors evaluated .and. then with use of correlation regression and principal component analysis the relationship . between production factors and : total productivity were investigated. Finally a comparison of factory performance in best and worst conditions were detected and the reasons for decrease or increase in each productivity index are expressed and the 'ways by which productivity can be increased are presented .
Total productivity in 1992 amounting to 1/032 constituted the lowest quantity while in l994 at
1/518 was the highest. The following are some of the factors affecting the total ,productivity: 'direct material productivity chip productivity. Capital productivity physical energy productivity as well as fix assets .
