The analyzing and modeling real lifetime data are crucial in many applied sciences including medicine, engineering, insurance and finance, amongst others. The two important one parameter lifetime distributions namely exponential and Lindley [2] are popular for modeling lifetime data from biomedical science and engineering. Recently, Shanker et al. [3] have conducted a comparative and critical s...

The vehicle routing problem (vrp) is related to service a number of customers with a fleet of vehicles. In real life, the applications of transportation, distribution and logistics are mostly studied as a research area for scientists and industrial practioners. In this study, the cargo distribution problem has been presented by using vrp procedures for a cargo company in Isparta City, Turkiye. ...

Since the early 1960s, the Hong Kong Telephone Company (HKTC)—the dominant firm in Hong Kong’s local telephone market—has undergone several regulatory reforms. The company has been subject to price control, rate-of-return regulation and price-cap regulation. This paper estimates the total factor productivity (TFP) growth of HKTC. The empirical results show that the estimated TFP growth of HKTC ...

This paper developed a stochastic programming model that integrated the most recent regulation rules of the Spanish peninsular system for bilateral contracts in the day-ahead optimal bid problem. Our model allows a price-taker generation company to decide the unit commitment of the thermal and combined cycle programming units, the economic dispatch of the bilateral contracts between all the pro...
