Abstract

Rainfall–runoff relationship is one of the most complex hydrological phenomena. A conventional neural network (NN) with backpropagation algorithm has successfully modelled various non-linear hydrological processes in recent years. However, the convergence rate of the backpropagation NN is relatively slow, and solutions may trap at local minima. Therefore, a new metaheuristic algorithm named as cuckoo search optimisation was proposed to combine with the NN to model the daily rainfall–runoff relationship at Sungai Bedup Basin, Sarawak, Malaysia. Two-year rainfall–runoff data from 1997 to 1998 had been used for model training, while one-year data in 1999 was used for model validation. Input data used are current rainfall, antecedent rainfall and antecedent runoff, while the targeted output is current runoff. This novel NN model is evaluated with the coefficient of correlation (R) and the Nash–Sutcliffe coefficient (E2). Results show that cuckoo search optimisation neural network (CSONN) is able to yield R and E2 to 0.99 and 0.94, respectively, for model validation with the optimal configuration of number of nests (n) = 20, initial discovery rate of alien eggs (painitial) = 0.6, hidden neuron (HN) = 100, iteration number (IN) = 1,000 and learning rate (LR) = 1 for CSONND4 model. The results revealed that the newly developed CSONN is able to simulate runoff accurately using only precipitation and runoff data.

Abstract

The Asian paradigm is more than just a demonstration of visually impactful behaviors and practices by hospitality establishments that can be explained by their different Asian cultural backgrounds and reinforced by training; it is focused on the customer, leveraging of the commercial environment while highlighting, not hiding, cultural and destination differences to give people more reasons to visit and repeatedly use their properties. This chapter examines to evaluate transferability of Asian paradigm in hospitality management concepts to non-Asian countries; what and how Asian paradigm in hospitality management can be transferred. For the detailed level on examination and discussion of transferability of Asian concepts, the chapter includes case of Shangri-La Hotels and Resorts for operators’ point of view.
