Transportation Route

This paper studies the problem of stowage planning within a vessel bay in a multiple port transportation route, aiming at minimizing the total container shifting fee. Since the access to containers is in the top-to-bottom order for each stack, reshuffle operations occur when a target container to be unloaded at its destination port is not stowed on the top of a stack at the time. Each container shift via a quay crane induces one unit of shifting fee that depends on the charge policy of the local container port. Previous studies assume that each container shift consumes a uniform cost in all ports and thus focus on minimizing the total number of shifts or the turnaround time of the vessel. Motivated by the observation that different ports are of nonuniform fee for each container shift, we propose a mixed integer programming (MIP) model for the problem to produce an optimal stowage planning with minimum total shifting fee in this work. Moreover, as the considered problem is NP-hard due to the NP-hardness of its counterpart with uniform unit shifting fee, we propose an improved genetic algorithm to solve the problem. The efficiency of the proposed algorithm is demonstrated via numerical experiments.

AbstractIn this paper, we propose and demonstrate a five-port optical router based on mode-selective property. It utilizes different combinations of four spatial modes at input and output ports as labels to distinguish its 20 routing paths. It can direct signals from the source port to the destination port intelligently without power consumption and additional switching time to realize various path steering. The proposed architecture is constructed by asymmetric directional coupler based mode-multiplexers/de-multiplexers, multimode interference based waveguide crossings and single-mode interconnect waveguides. The broad optical bandwidths of these constituents make the device suitable to combine with wavelength division multiplexing signal transmission, which can effectively increase the data throughput. Measurement results show that the insertion loss of its 20 routing paths are lower than 8.5 dB and the optical signal-to-noise ratios are larger than 16.3 dB at 1525–1565 nm. To characterize its routing functionality, a 40-Gbps data transmission with bit-error-rate (BER) measurement is implemented. The power penalties for the error-free switching (BER<10−9) are 1.0 dB and 0.8 dB at 1545 nm and 1565 nm, respectively.

This paper describes an approach for improving cyber resilience through the synthesis of optimal microsegmentation policy for a network. By leveraging microsegmentation security architecture, we can reason about fine-grained policy rules that enforce access for given combinations of source address, destination address, destination port, and protocol. Our approach determines microsegmentation policy rules that limit adversarial movement within a network according to assumed attack scenarios and mission availability needs. For this problem, we formulate a novel optimization objective function that balances cyberattack risks against accessibility to critical network resources. Given the application of a particular set of policy rules as a candidate optimal solution, this objective function estimates the adversary effort for carrying out a particular attack scenario, which it balances against the extent to which the solution restricts access to mission-critical services. We then apply artificial intelligence techniques (evolutionary programming) to learn microsegmentation policy rules that optimize this objective function.

Program solver is one of the most widely used software to solve problem related to transportation. Transportation model determines distribution cost of a product from port of origin to port of destination. This research purpose is intending on analyzing the application of program solver in minimizing fish distribution cost from suppliers to industrial centers. The result showed that efficiency distribution cost of tuna was Rp. 757.983.424,- and the efficiency distribution cost of small pelagic fish was Rp. 268.012.767,-. Distribution cost of tuna from Bitung to Surabaya is more efficient, distribution cost of tuna from Ternate to Makassar is more efficient, distribution cost of tuna from Medan to Surabaya is more efficient, distribution cost of tuna from Banyuwangi to Jakarta is more efficient, and distribution cost of tuna from the other ports of origin are more efficient to Makassar, Jakarta, Surabaya and the other ports of destination. Distribution cost of small pelagic fish from Bitung to Makassar is more efficient, distribution cost of small pelagic fish from Ternate to Surabaya is more efficient, distribution cost of small pelagic fish from Medan to Makassar is more efficient, distribution cost of small pelagic fish from Banyuwangi to Makassar and Surabaya is more efficient, and distribution cost of small pelagic fish from the other ports of origin are more efficient to Jakarta and Surabaya. Therefore, fish distribution from port of origin should be focused to a particular destination port in order to get more efficient distribution cost and stable fish supply in the destination area.

Siitperf is the World’s first free software RFC 8219 compliant SIIT (also called stateless NAT64) tester written in C++ using DPDK, which is also suitable for benchmarking IPv4 / IPv6 network interconnect devices in RFC 2544 / RFC 5180 compliant ways. Originally, siitperf followed RFC 2544 Appendix C.2.6.4 test frame format resulting in “hard coded” source and destination UDP port numbers. RFC 4814 Section 4.5 recommended random, uniformly distributed source and destination port numbers, which can make a very significant difference, when the DUT (Device Under Test) has multiple CPU cores, what is very common today. Therefore, adding this feature to siitperf is essential to be able to produce meaningful benchmarking results. In this paper, we disclose the design, implementation and performance estimation of this extension of siitperf.

Spatial planning, taking into account the configuration of the surface, i.e. its shape (relief) and the presence and mutual location of objects and points of characteristic water ports, is a derivative of several natural, economic, market, technical, social and political factors. It depends on the destination port, the planned structure of trade in cargo, the forecasted traffic of ships, passageways, the technology of reloading used, as well as on the anticipated demand for the development of shipping and trade by sea and inland waterway. The article analyzes the transport accessibility of the Port of Gdynia through the construction of a dock to determine the proposals for improving the conditions of transported cargo.

Heavy cargo units with a relatively reduced footprint area require a support surface large enough to transfer the forces onto the largest possible surface and/or the main stiffening (longitudinal and transverse) in order to not collapse or overstress the ship’s structure and, consequently, put the ship, the cargo, and the crew at risk. For that reason, it is necessary to project stowage and securing systems (including bedding design) to ensure that, by applying the principles of good seamanship and securing practices, the shipment is maintained in a safe condition throughout the trip until destination port arrival. Despite the increase in project cargo shipments in recent years, in many cases, International Maritime Organization (IMO) regulations are followed by default. The main purpose of this paper, thus, is to highlight certain shipments for which IMO guidelines should be taken into account in future revisions. This is done through what was considered innovative project cargo on a particular ship due to its special characteristics. To this end, because of limitations found in the IMO CSS Code regarding acceleration and force calculations, it was necessary to resort to the internationally accepted guidelines of one of the strictest classification societies.
