Sustainability has become a significant concern worldwide in recent decades. There seems to be implicit competition among firms for better sustainability performance. Like any other firm activity, undertakings require resources and their efficient use achieve the desired Firms may hesitate undertake initiatives due underlying costs, leading question of how they are practices. Relying on data fr...

On the southern coast of South Korea, dark-banded rockfish, sea bass, and red seabream are caught by single-line fishing. In particular, bass in Jeollanam-do region using gear with attached fishing hooks, such as long-line gear, live shrimp bait. The objective this study was to compare catch efficiency two types (naturally grown Shiba [Metapenaeus joyneri] cultured whiteleg [Litopenaeus vanname...

Efficiency of industrial production lines is crucial as it results in an improved production and utilization of available resources. Factors contributing to production line efficiency are manpower utilization and machine efficiency. Measuring the machine efficiency and man power utilization should be on-line, accurate and truthful. The management should be able to look for relevant production d...

This paper presents a multi-objective simulated annealing algorithm for the mixed-model assembly line balancing with stochastic processing times. Since, the stochastic task times may have effects on the bottlenecks of a system, maximizing the weighted line efficiency (equivalent to the minimizing the number of station), minimizing the weighted smoothness index and maximizing the system reliabil...

A unique line of Duroc pigs was established by intensive selection for increased lean growth efficiency. The objective of this study was to determine the influence of this selection strategy on fresh pork quality traits. Two lines of Duroc pigs originating from the same foundation herd were evaluated. One line was selected for lean growth efficiency over five generations (Select line), and the ...

This paper studies the allocative efficiency of two non-price allocation mechanisms — the lottery (random allocation) and the waiting-line auction (queue system) — for the cases where individuals possess identical time costs (the homogeneous case), and where time costs are correlated with valuations (the heterogeneous case). The relative efficiency of the two mechanisms is shown to depend criti...
