The purpose of this study is to track the introduction of the irrigation agency (Watershappen) in the Vorstenlanden area Surakarta and Yogyakarta as well as effects on the relationship between farmers, farmers and plantation owners. In addition, this study aims to understand the patterns of institutional change and the water distribution system in the Vorstenlanden region and consequently on agriculture and plantation. State involvement in the problem of water distribution in the Vorstenlanden area causing a collision between a proportional system that has been done by the traditional farmers with absolute system applied state. As a result, irrigation conflicts arise between plantation because of the use of a watershed point for some plantations. Conflicts between plantations and farmers because of water scarcity due to the autonomy of the estate in the distribution of water to agricultural land and conflicts between farmers as water encroachment without the knowledge of other farmers.

Impact Duration

Understanding the impact and duration (consequences) of different component failures (cause) in a water supply and distribution system (WSDS) is a critical task for water utilities to develop effective preparation and response plans. During the last three decades, few efforts have been devoted to developing a visualization tool to display the relationship between the failure cause and its consequences. This study proposes two visualization methods to effectively show the relationship between the two failure entities: A failure cause–impact–duration (CID) plot, and a bubble plot. The former is drawn for an effective snapshot on the range (extent) of failure duration and the impact of different failures, whereas the latter provides failure frequency information. A simple and practical failure classification system is also introduced for producing the two proposed plots effectively. To verify the visualization schemes, we collected records of 331 WSDS component failures that occurred in South Korea between 1980 and 2018. Results showed that (1) the proposed CID plot can serve as a useful tool for identifying most minor and major WSDS failures, and (2) the proposed bubble plot is useful for determining significant component failures with respect to their failure consequences and occurrence likelihoods.

The Relationship

Quantum key distribution (QKD) allows authenticated parties to share secure keys. Its security comes from quantum physics rather than computational complexity. The previous work has been able to demonstrate the security of the BB84 protocol based on the uncertainty principle, entanglement purification and information theory. In the security proof method based on entanglement purification, it is assumed that the information of Calderbank–Shor–Steane (CSS) error correction code cannot be leaked, otherwise, it is insecure. However, there is no quantitative analysis of the relationship between the parameter of CSS code and the amount of information leaked. In the attack and defense strategy of the actual quantum key distribution system, especially in the application of the device that is easy to lose or out of control, it is necessary to assess the impact of the parameter leakage. In this paper, we derive the relationship between the leaked parameter of CSS code and the amount of the final key leakage based on the BB84 protocol. Based on this formula, we simulated the impact of different CSS code parameter leaks on the final key amount. Through the analysis of simulation results, the security of the BB84 protocol is inversely proportional to the value of [Formula: see text] and [Formula: see text] in the case of the CSS code leak.

The Relationship

The accurate evaluation of distribution system reliability plays an important role in distribution system planning. The existing method doesn’t consider the influence of different inclement weather. This paper proposed a new method for evaluation of distribution system anti-disaster ability in inclement weather. Firstly, the influence of the system components in inclement weather was analyzed according to the physical situation; then the relationship between the breakdown probability of the components and the meteorological parameters was studied on the basis of the components quality. Secondly, considering the characteristics of distribution system, the probability of continuous failure was discussed by the minimal path method. Finally the evaluation indices were introduced to represent the distribution system anti-disaster ability. The simulation results show the laws between the distribution system’s anti-disaster ability and the changing meteorological parameters.

This paper presented a formal analysis for the alternative of logistics centralization and decentralization policy in a two-echelon distribution system. First, functions of transportation and inventory costs under different policies in the system were developed. Second, the differences between transportation and inventory costs were compared, and the relationship between transportation and inventory cost difference was analyzed through a balance ratio. At last, some indicators were derived to measure the level of demand uncertainty, the amount of retailers and the size of customer orders. It shows that the optimal logistics policy can be determined as a tradeoff between transportation and inventory costs. And the indicators can provide a basis for selecting the optimal logistics policy.

The Relationship

This study determined the relationship between client choice and client food security status, and how the relationship was affected by household type. Data was obtained from the Voices for Food Project. Among the various goals for that project, was the goal of guiding pantries to transition from a traditional food distribution system to a client-choice system where clients could select the kinds of foods they preferred. The results showed that pantry client choice satisfaction was significantly associated with greater food security status (X2 (1, N = 685) = 8.81, p = .003). There were no differences between household type and choice satisfaction (X2 (1, N = 685) = 0.81, p = .366 However, differences existed between household type and food security status (X2 (1, N = 685) = 22.56, p [less than] .001), the households with children were less likely to be food secure. In predicting food security by client choice satisfaction, being satisfied and being older resulted in significantly higher odds for food security (choice satisfaction OR: 3.20; 95 [percent] CI: 1.54, 7.54, age OR: 1.02; 95 [percent] CI: 1.01, 1.04). Whereas, having children in a household yielded lesser odds for food security (households having children OR: 0.52; 95 [percent] CI: 0.34, 0.81). The sex of householder did not play a role in predicting household food security based on choice satisfaction (sex OR: 1.01; 95 [percent] CI: 0.69,1.49). Provision of client choice in food pantries could improve client food security status and could be added support to governmental food assistance programs targeted at addressing food insecurity in the nation.

The Relationship

This chapter primarily deals with the relationship between the marketing mix and the channel strategy of the companies. The distribution system is influenced by product, price, and promotion of the brand. The choice of the distribution system also influences the product, price, and promotion strategy of the brand. The chapter will discuss in detail how each of the factors of product, price, and promotion are correlated with the channel strategy of the company. It is seen that the product along with the market determines the distribution strategy and the channel choices and strategies are influenced by the stage of the product life cycle. Pricing has always been a very important aspect of marketing a product. It assumes more importance as the price of the product also goes on to influence the margins of the intermediaries. It can be easily understood that the margins on a product impacts upon the commitment of the intermediaries or channel members. This in turn influences the willingness of the channel members to push the brand or the product to their customers. The channel members also expect a lot of support from the company in terms of advertisements or other consumer or trade promotion schemes. The quantum of support is dependent on the capacity of the company and the type of product and market they are operating in. This chapter also discusses about the franchise system and the electronic channel system which are now part of the channel strategy of almost all large companies. The characteristics of these channels along with their advantages and disadvantages are also discussed in detail.
