Izvod U radu je predložena metodologija izbora rudnog ležišta primenom TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) i AHP metode (Analytic Hierarchy Process UVODVišekriterijumsko odlučivanje (multiple criteria decision making -MCDM) se generalno može opisati kao proces izbora jedne iz skupa raspoloživih alternativa, koja najefikasnije ispunjava postavljene ciljeve. Tokom poslednje dve decenije značajna pažnja je usmerena na razvoj i primenu MCDM metoda u rešavanju problema i dilema u oblasti upravljanja prirodnim resursima. Primeri se mogu naći u mnogim časopisima [1,2,3,4,5,6,7]. Značajan broj radova se bavi primenom ovih metoda u oblasti obnovljivih resursa i održivog razvoja [8,9,10]. Ali šta je sa primenom MCDM metoda u odlučivanju u mineralnoj industriji i metalurgiji? Neki autori su se bavili ovim pitanjima.Izbor metode rudarenja je veoma česta tema u oblasti mineralnih resursa. Alpay i Yavuz su razmatrali sistem za podršku odlučivanju u izboru metode podzemnog rudarenja [11]. Naghadehi et al. su učinili nešto slično. Oni su predložili fazi AHP za određivanje optimalnog metoda rudarenja u iranskom rudniku [12]. Azimi et al. su rangirali strategije rudarskog sektora pomoću AHP i TOPSIS metode u okviru . Samimi Namin et al. su predložili novi model, baziran na fazi odlučivanju, za izbor metoda rudarenja [14].U ovom radu je predloženo korišćenje TOPSIS-a, između ostalih MCDM metoda, u preliminarnoj analizi za izbor odgovarajućeg rudnog ležišta za eksploataciju. AHP je upotrebljen za određi-vanje težina kriterijuma. Rad je organizovan na sledeći način: u drugom delu pažnja je usmerena na TOPSIS i AHP; u trećem delu je prikazan numerički primer koji je baziran na realnim podacima; a zatim sledi zaključak u četvrtom delu. AHP je predložio Saaty [18,19] za oblikovanje subjektivnih procesa odlučivanja baziranih na više kriterijuma u hijerarhijskoj strukturi. Saaty je konstatovao da je najkreativniji zadatak u odlučivanju biranje faktora koji su važni za određenu odluku. U AHP-u donosilac odluke strukturiše izabrane faktore hijerarhijski, prema opadajućem redosledu od sveukupnog cilja do kriterijuma, sub-kriterijuma i alternativa na uzastopnim nivoima [20]. Ovaj model je takođe pogodan za determinisanje relativnih težina kriterijuma u odgovarajućoj hijerarhijskoj strukturi. Postoje brojne metode za determinisanje težina u AHP-u. Neke od njih su:• metod aritmetičkih sredina normalizovanih kolona (average of normalized columns -ANC),• metod normalizovanih suma redova (normalization of row average -NRA), i • metod normalizovanih geometrijskih sredina redova (normalization of the geometric mean of the rows -NGM) [21]. TOPSIS i AHP su dokazano korisni za modeliranje i analizu različitih situacija u odlučivanju u raznim poljima nauke i tehnologije [15,18]. Navedene metode su usmerene na rešavanje problema koji su vezani za izbor jedne alternative od više ponuđenih. AHP metod je pogodan za primenu i kod opipljivih i kod neopipljivih kriterijuma, naročito kada subjektive procene pojedinaca čine v...

Economic potential of agroforestry for public recreational parks

The availability of public recreational facilities is being threatened by growing demands, limited supplies, and declining government funding. In response to these pressures, the economic potential of agroforestry for supplementing operating budgets of public recreational parks is examined in a case study park consisting of 324 hectares. Agroforestry enterprises native to the area were selected for development on 70 hectares of the site. Linear programming was used to determine the optimum combinations of 23 agroforestry regimes composed of the following activities: 1) conventional forestry planting, tree density of 1682 trees/hectare, 2) the selected agroforestry planting with hay, tree density of 1495 trees/hectare, 3) the selected agroforestry planting with grazing, 4) hay production, and 5) rental of pasture for grazing. The objective function of the study was to maximize the net present value of the study site subject to land, labor, capital, and minimum annual income constraints. The preferred optimal regime generated $1782 per hectare from an agroforestry planting configuration of 1495 trees/hectare with 75 percent hay, 25 percent grazing, and no annual income requirements. Minimum annual income requirements of $2400 and $4800 were feasible but suboptimal from a net present value criteria. The study found that agroforestry could be used to privatize selective activities of public recreational parks and thus enable public agencies to provide these facilities more effectively.

“…Previously, a wide range of mathematical techniques were developed to examine economic, environmental and ecological impacts of various land-use actions, and thus aid decision makers in formulating effective land-use allocation policies (Collins and Barry, 1986;Mendoza, 1987;McDonald, 2001;Ligmann-Zielinska et al, 2008;Mitsova et al, 2011). For example, McDonald (2001) used a cost-benefit analysis method for the assessment of local land-use allocation decisions based on a sequence of microeconomic models (e.g., Cobb-Douglas Production Function).…”

A hybrid inexact optimization model for land-use allocation of China

Land scarcity has become the prominent obstacle on the way to sustainable development for China. Under the constraints of land shortage, how to allocate the finite land resources to the multiple land users in China considering various political, environmental, ecological and economic conditions have become research topics with great significance. In this study, an interval fuzzy national-scale land-use model (IFNLM) was developed for optimizing land systems of China. IFNLM is based on an integration of existing interval linear programming (ILP), and fuzzy flexible programming (FFP) techniques. IFNLM allows uncertainties expressed as discrete interval values and fuzzy sets to be incorporated within a general optimization framework. It can also facilitate national-scale land-use planning under various environmental, ecological, social conditions within a multi-period and multi-option context. Then, IFNLM was applied to a real case study of land-use planning in China. The satisfaction degree of environmental constraints is between 0.69 and 0.97, the system benefit will between 198.25 × 10 12 USD and 229.67 × 10 12 USD. The results indicated that the hybrid model can help generate desired policies for land-use allocation with a maximized economic benefit and minimized environmental violation risk. Optimized land-use allocation patterns can be generated from the proposed IFNLM. Keywords: land-use planning; uncertain model; interval linear programming (ILP); fuzzy flexible programming (FFP); environmental protection; interval fuzzy national-scale land-use model (IFNLM)
