In this study, we consider the mechanism design problem for the optimal allocation of fishing quotas at different total allowable catch (TAC) levels. An age-structured fish population model is employed. Fishing technologies are embedded in the economic model as a key determinant. As a result, we showed that the quota allocation mechanism is important to minimize the impact of fishing on total fish biomass or achieve maximum sustainable yield (MSY). Moreover, we indicated technology-based optimality conditions for allocation of quotas at different TAC levels, which minimize the impact of fishing on total fish biomass or enable us to achieve MSY. Under the consideration that the fishermen fulfill their remaining quotas through capturing untargeted (less revenue-generating) fish after the targeted fish population is fully caught, the fix ratio of the catch of targeted fish to untargeted fish is not valid anymore. Concordantly, we indicated technology-based optimal quota levels, including the interior solutions. In the EU, TACs are distributed among states according to the principle of ‘relative stability’ which prescribes that the fishing quotas should be allocated based on historical catches of the EU states. In this context, rather than allocating the quotas based on historical catches, our main suggestion is that the structure of the fishing industry should be considered for allocation of quotas to provide the sustainability of EU fisheries and achieve responsible and effective management of the fishing industry in the EU.

Resource investment problem with time/resource trade-offs Çolak, Erdem; Azizoğlu, Meral; Department of Industrial Engineering (2011) In this study, we consider a resource investment problem with time/resource trade-offs in project environments. We assume each mode of an activity is characterized by its processing time and resource requirement and there is a single renewable resource. Our aim is to minimize the maximum resource usage, hence the total amount invested for the single resource. We formulate the problem as a mixed integer linear model and find optimal solutions for small sized problem instances. We propose several lower boundi...
A linear programming approach to quaity improvement project and product mix selection under inspection error and rework Şarbak, Nedret; Köksal, Gülser; Department of Industrial Engineering (2006) In this study, the effect of inspection error on the product mix and quality projects selection in a manufacturing environment where rework and inspection errors exist is examined. It is assumed that the products (items) for which rework is necessary are reprocessed at a separate work center and 100% inspection is performed for the products both after rework and processing operations. Markov chain approach is used to compute yield and rework rates. In addition, nominal-the-best type of a quality loss functi...
Two-sided assembly line balancing models and heuristics Arıkan, Uğur; Kırca, Ömer; Department of Industrial Engineering (2009) This study is focused on two-sided assembly line balancing problems of type-I and type-II. This problem is encountered in production environments where a two-sided assembly line is used to produce physically large products. For type-I problems, there is a specified production target for a fixed time interval and the objective is to reach this production capacity with the minimum assembly line length used. On the other hand, type-II problem focuses on reaching the maximum production level using a fixed assem...
A new approach to generating non-permutation schedules for flowshops with missing operations Tabalu, Metin; Şen, Tayyar; Department of Industrial Engineering (2006) In this study, non-permutation flowshops with missing operations are considered. The primary performance criterion is the total cycle time (i.e. makespan) and the secondary criterion is the total flowtime. In order to obtain the schedule with minimum makespan and minimum total flowtime, non-permutation schedules are being generated instead of permutation ones by permitting multiple jobs bypassing stages where misisng operations occur. A heuristic algorithm has been developed in order to generate non-permuta...
Site Specific Relationship for Strain Dependent Shear Modulus and Damping Using In Situ V S and High Strain Cyclic Test Results Zehtab, Kaveh Hassan; Yılmaz, Mustafa Tolga (2016-08-18) This study suggests a practical method for estimating site-specific strain dependent shear modulus and damping. The method uses in-situ shear wave velocity measurements and commercial cyclic laboratory tests on higher strains (i.e., 0.5% to 1%) in which the effect of disturbance is less significant. Shear modulus calculated using in-situ shear wave velocity and at higher cyclic shear strain, is used for building a hyperbolic relationship for shear stress and strain. Modified Masing's rule and the experiment...
