  • annualized hours as a capacity planning tool in make to order or assemble to order environment an Agricultural Implements company case
    Production Planning & Control, 2001
    Co-Authors: Eduardo Vila Goncalves Filho, Josadak Astorino Marcola

    Abstract:

    Capacity planning is one of the most important elements for an efficient production planning and control system. It is even more important when the main strategies to fulfil sales requirements are make-to-order (MTO) or assemble-to-order (ATO). Neither MTO or ATO companies keep finished products in stock which means that production level is driven by actual sales figures. Therefore, it is very important to have an available capacity as flexible as possible to meet sales requirements. Annualized hours (AH) is a work time control system that helps in increasing the flexibility of available capacity. The main rule of the AH system is to hire employees to work a certain number of hours on a yearly basis. Following some other pre-defined rules and limits, the AH system allows a company to adjust weekly available time in order to reduce idle capacity or to fulfil requirements that could mean overtime. This paper proposes a linear programming model to plan the operations using AH. This model has been implemented…

  • Quantifying life cycle inventories of Agricultural field operations by considering different operational parameters
    The International Journal of Life Cycle Assessment, 2019
    Co-Authors: Giuseppe Tassielli, Pietro A. Renzulli, Seyed Hashem Mousavi-avval, Bruno Notarnicola

    Abstract:

    Purpose The ability to estimate fuel and lubricant consumption as well as depreciated weight of Agricultural machinery used for field operations is very useful for energy and environmental analyses. In this study, life cycle inventory data of Agricultural field operations were established by considering different parameters of such operations. Methods Agricultural operations considered in this study include tillage, cultivation, planting, harvesting and post-harvest operations. For these operations, the fuel and lubricant consumption as well as depreciated weight of tractors, combine harvesters and Agricultural Implements was estimated by considering different operational parameters such as tractor power, field condition, depth of operation, soil condition, tractor type, operational capacity of machine, width of operation and speed. Technical standards were used to estimate different types of power required for most Agricultural operations (drawbar power, rotary power and motion power). The standards were then used to evaluate the variability of the fuel and lubricant consumption as well as depreciated weight of the Implements by varying the aforementioned parameters. Results and discussion The results were compared to those that can be calculated with other approaches for life cycle inventory analysis of Agricultural operations. Such comparison indicates that by using different parameters, representing the diverse local conditions of different field operations, a great variability of the results is obtained. For instance, diesel fuel consumption of tillage operations ranges from 12.6 to 76.0 L ha^−1, with an average of 34.15 L ha^−1 and standard deviation of 11.7 L ha^−1. Such representativeness of the different conditions of each field operation cannot be modelled with other tools or via the use of standard LCI datasheets. Conclusions The final result of this study is a novel approach for the life cycle inventory analysis of Agricultural operations, in terms of fuel and lubricant consumption and of depreciated weight of the machines, which are estimated by simply selecting the operational parameters which best represent the effect of local conditions.
