Operational Research - Essay Example The numerous techniques of operations research include mathematical optimization, statistical analysis and mathematical simulation. Because of their capability to assist in decision making, operations research techniques are more often employed in manufacturing companies. These techniques have been employed to determine the most suitable places to locate new facilities such as a factory or a warehouse, identifying appropriate development paths for sections of the telecommunications. One of the most applied operations research techniques is linear programming. The use of linear programming was first proposed in 1951 to institute least-cost mixtures of livestock rations and food stuffs. This linear program reduces the expense of the mixture while some identified levels of nutritional necessities symbolize the model’s constraints. Additionally, in 1954, linear programming was proposed as a way of solving crop rotation problems (Hayashi, 2007: 21). In this case, the objective func tion symbolizes the gross margin linked to the cropping pattern while constraints link to the accessibility of capital such as land, machinery, and working capital. The idea of the use of linear programming has been used extensively in planning and managing agricultural resources on a farm. Extension of linear programming engross binary and integer platforms for applications in which it is not reasonable to allocate incessant values to the decision variables, for instance, the number of tractors and labour workers. The inter-temporality essential to many agricultural resolutions, particularly those entailing perennial crops, has necessitated the use of multi-period models. Risk and uncertainty calls for methods such as dynamic programming, Markov chains and Monte Carlo Simulation (Cheema, 2005: 43). Brazil is a huge producer of sugarcane, alcohol fuel and sugar. In order to keep the production

The Role of Women in Australian Society Essay Example | Topics and Well Written Essays - 2000 words - 1

The Role of Women in Australian Society - Essay Example Finally, she has seen a period where she has entered the labor force, therefore has money of her own, and this, in turn, has made her less beholden to the man she married. This is where the current state of woman is, and it has resulted in a high failure rate for marriages. This paper will examine how the roles of women have changed in Australian society, both in and outside of marriage, and how these roles have affected marriage and divorces in the last century. The largest change for women, in the realm of marriage, is the fact that patriarchy has shifted. For instance, one may view the movie The Piano for an example of how things used to be for women in Australia and New Zealand. In The Piano, the woman in the marriage was in the marriage because it was arranged, and, although it was evident that the main character, Ada, had a husband who wanted a â€Å"real† marriage, this never manifested. It was quite simply obvious that Alistair, the husband in this scenario, saw Ada as a way to bolster his social standing and really nothing more (The Piano). The Piano reflects a time in Australian history, indeed, in the history of the world, where women were regarded as property, and, because of this, fathers were able to force their daughters into loveless marriages. This reflects the standing of women in general during the 1850s. While The Piano reflects a time during the 19th Century, this paper will deal with the changing status of women during the 20th Century, but it is a helpful touchstone nonetheless.
