No full textVehicle Routing Problems (VRP) are used to find the most suitable routes
for fulfill the delivery and pickup demands of the companies. In real
life, new pickup requests received by routed vehicles will provide a
significant reduction in transport costs. As a result, a new
mathematical model called as Dynamic Vehicle Routing Problem with
Simultaneous Pickup and Delivery (DVRPSPD) has been developed for new
pickup requests received by routed vehicles. Small and medium-sized
problems were generated and solved for evaluate the effectiveness of the
proposed model. The results obtained with the mathematical model were
evaluated. The solution time increased exponentially as the problem size
increased. In this study, heuristic algorithms were used to solve the
problem in a short time. A new algorithm called Random Iterative Local
Search Variable Neighborhood Descending (R-ILS-VND) algorithm has been
developed. Order of the neighborhood structures was changed continuously
by decreasing permutation method at R-ILS-VND algorithm. In order to
evaluate the effectiveness of the developed algorithm, the results were
compared to the mathematical models results. When the results are
analyzed, the heuristic algorithm has similar results to the
mathematical model. Finally, the medium and large size problems were
solved by using the proposed R-ILS-VND algorithm and the results were
analyzed

Sistemde, devre için bir türbin tasarlanarak üretilmiştir. Türbin girişinde soğutucu akışkanın basıncı yükseltilerek türbinin enerji üretmesi sağlanmıştır. Türbin çıkışında soğutucu akışkan yoğuşturularak çevrime tekrar alınmıştır. Geliştirilen sistemde 4 HP ve 6 HP güçlerinde iki kompresör kullanılıp, kompresörlerin hızı invertörler vasıtasıyla kontrol edilmiştir ve sistem için kontrol teknolojisi geliştirilmiştir. Sistemin tamamı, mikrodenetleyici ile otomatik olarak kontrol edilmiştir. Alternatör hızı 200 devir/dakika ve üretilen elektrik gücü 66,6 W olarak ölçülmüştür. Sistemin çalışması için harcanan enerjinin %2,08’i sisteme geri kazandırılmıştır. Böylece, bir enerji dönüşümü sağlanmıştır.In this study, the design and experimental study of the system of generating electricity using heat energy discharged from the condenser in vapor compression cooling systems has been performed. In the system, a turbine is designed and manufactured for the circuit. The pressure of the coolant was increased at the turbine inlet, the turbine was provided to generate energy. At the turbine outlet, the refrigerant was condensed and taken back to the cycle. In the developed system, two compressors with 4 HP and 6 HP powers were used, the speed of the compressors was controlled by inverters and control technology was developed for the system. The entire system was automatically controlled with a microcontroller. The alternator speed was measured as 200 rpm and the electrical power produced was 66.6 W. 2.08% of the energy spent for the operation of the system was recycled to the system. Thus, an energy transformation has been achieve
