Abstract:DEA (Data Envelopment Analysis) represents one of the most important and latest models of the applications of mathematical programming in the economy, which is used to measure and improve the efficiency of production activities within a company (agricultural farm) or companies (farms) within a region. In this study, the DEA model was applied to analyze and improve the efficiency of 16 units in Lushnja district, Albania, for the production of greenhouse tomato culture. The output selected is the tomato yield cultivated in greenhouses (q/are), and the included inputs are manure (q/are), fertilizer (q/are), liquid crystal fertilizer (q/are), pesticides (q/are) and irrigation (m3/are). The CCR model based on the authors Charnes-Cooper-Rhodes is input-oriented. The DEA model was applied to minimize the quantity of inputs used to produce the same level of output (production of tomato culture). Once the problem arises as a linear programming problem with constraints, dictated by the shape of the CCR model, it is solved with a computer program called Solver solution. For the inefficient units, the linear combination of efficient units was determined, which consists a more efficient composite unit than the inefficient unit. From the analysis, the Municipality of Golem resulted with a DEA efficiency of 88.3% (inefficient by DEA) and to obtain the actual yield of 78 (q/are) it has used these amount of inputs: 90 (q/are) manure, 1.8 (q/are) fertilizer, 1.5 (q/are) crystalline fertilizer, 0.65 (q/are) pesticides and 45 (m3/are) water. Thus, through this model, it was possible to improve the efficiency of the unit while the used composition values were found to have the same performance and yield. In particular, we found out that the amount of inputs used were: 79.447 (q/are) manure, 1.562 (q/are) fertilizer, 1.324 (q /are) crystalline fertilizer, 0.062 (q/are) pesticides and 39.72 (m3/are) water. As a result, with these amount of inputs used unit 13 (Municipality of Golem), the efficiency is 100%. The main goal of using DEA is that the inefficient unit must be capable of acting as efficient as the hypothetical entity comprising, formed by a linear combination of efficient units. For each inefficient unit, DEA model identifies the source and the level of inefficiency for each of the inputs and outputs used. This model has a wide use in various fields of production economics.
