ABSTRACT Before performing any financial analysis costs must be calculated. These costs should allow the planning and control over the use of the machines as well as the comparison between different investments alternatives since this is easily calculated. Generally the operating costs of forest harvesting machines are estimated until the maximum of 25,000 hours of work, and it is not possible to know whether the activity remains profitable thereafter or not. For this reason the objective of this study was to evaluate the costs from cutting activities and wood processing carried out by a forestry tractor harvester up to approximately 30,000 hours of work. Ten forest machines composed of two models of harvester (John Deere, model 1270D and 1470D) were used. A spreadsheet provided by a forestry company located in the state of Minas Gerais, containing the necessary data to estimate the operating cost of the machines and subsequent achievement of the sensitivity analysis was used. The operating cost was obtained by the sum of the fixed and variable costs. For sensitivity analysis the variation ± 20% of the most representative elements of the total cost of the machine was performed. The results for the operating cost of the harvester and forwarder was U.S. $ 190.85 h-1. Costs for repairs and maintenance, labor, fuel, and depreciation represented approximately 90% of the total cost of the machine. Despite the fact that the age of the machine has a direct influence on its operating cost, the costs did not behave in a linear fashion over the years.

The Impact

The case helps students to understand the emerging concept of linear and circular economies. It facilitates to examine the implications of circular business models such as remanufacturing on operations management decisions. It also introduces them to the concept of total cost of ownership and impact of remanufacturing on reducing total cost of ownership. The cases help students to evaluate the challenges and opportunities of remanufacturing business in emerging economy like India. This case is among the first few cases on the application of circular economy principles in context of heavy-duty and off-road sector and the impact of these principles on product design and production planning and control decisions.

Abstract Forest harvesting equipment purchase costs in 1984 were determined by a survey of equipment dealers and manufacturers operating in the South. Based on delivered purchase prices, fixed costs for equipment ownership were calculated using machine rate formulas. Equipment operating costs were estimated based on general guidelines, fuel consumption data, and historical records. The fixed and operating cost data can be used when considering equipment investments and analyzing actual or potential harvesting systems.

The Impact

This study aims to know the planning to control the project activities during the implementation phase. The success rate or failure of a project leads to less mature planning and less effective controls, resulting in project delays, increased implementation costs and lower quality. To set the time for completion of the project to be more effective and efficient can use PERT and CPM methods so as to reduce the impact of delays and swelling of implementation costs. The PERT (Program Evaluation and Review Technique) method is a method that aims to reduce as much as possible delays, Production, and coordinate various parts of a job thoroughly and accelerate the completion of the project. While the CPM method is a method of planning and control projects that have cost data in the past. Based on the analysis results show the initial duration of the project with duration of 180 days (6 months) with the total cost of Rp. 73.599253,59. As a result of overtime work system, the duration of its activities to be 164 days with project cost of Rp. 55,089,267.07.

Engine Maintenance

The Allison projected engine operating cost technique allows calculation of engine maintenance direct operating costs for various maintenance concepts and flying programs. Cost effects resulting from predicted or measurable effects of environment or mission constraints can also be calculated. This technique may be used to develop sensitivity analysis around nominal cost driver values. The technique discussed was designed for use with a hand-held programmable calculator.

Pastoral Farming

The growth in horticultural and some industrial development in selected areas of Northland has led to a need for more specific and careful planning and control of limited resources in a number of major catchments. The potential irrigation demands for horhculture comprise over 60% of Northland's potential water requirements. By contrast, farm water supply needs are only 11% of these needs. Because of their importance to the Northland economy, and in the legislation these needs are given a high priority in water resource management planning. Land uses, including pastoral farming, require careful operation to reduce diffuse sources of pollution.
