In this paper, we study a distributed blocking flowshop scheduling problem（DBFSP） that is an extension of the traditional blocking flowshop scheduling problem（BFSP）, in which an additional decision of which factory to process each job. We propose an iterated greedy（IG） algorithm to minimize makespan among all the factories. First of all, an effective initialization method based on the PW algorithm is used in order to make better use the problem-specific characteristics. Then, an enhanced construction method is developed to further improve the solution obtained at each iteration. At last, after calibration of algorithm parameters, comparison of algorithms is carried out using the well-known 720 instances from the literature. The results demonstrate the effectiveness of the proposed IG algorithm for solving the DBFSP with makespan criterion.

第三十九届中国控制会议

The distributed blocking flowshop scheduling problem（DBFSP） that is an important generalization of the traditional blocking flowshop scheduling problem（BFSP）, in which the blocking constraint has to be considered. The NEH heuristic is regarded as the best constructive heuristic for the permutation flowshop scheduling problem. Naderi and Ruiz proposed the NEH2 for the distributed permutation flowshop scheduling problem by adding a factory assignment rule to the Nawaz-Enscore-Ham（NEH） heuristic. In this paper, a priority rule is first presented for generating initial sequence for the NEH2. Then, the proposed rescheduling operator is applied in NEH insertion procedure. Additionally, we generated a sequence containing all job twice, and then the solution for the problem is constructed by applying the NEH insertion procedure on each element of the sequence. Based on the above ideas we proposed three NEH-based heuristics, namely NEH2 E, NEH2 Een and NEH2 EE. Computational results demonstrate that the proposed heuristics perform significantly better than the original NEH2.

To produce high-affinity monoclonal antibodies against pesticide carbofuran, and the develop immunochemical assays for people＇s health and environmental protection, the hapten 4-[[（2,3-dihydro-2,2-dimethyl-7-benzofuranyloxy） carbonyl]- amino]-butanoic acid （BFNB） of carbofuran was synthesized and Balb/c mice were immunized by the hapten-carrier （BFNB-bovine serum albumin, BFNB-BSA） conjugates. The splenocytes of immunized mice were fused with Sp2/0 cells and the cultural supernatants of hybridoma cells were screened by the indirect enzyme-linked immunoabsorbent assay （ELISA）, based on BFNB-ovoalbumin conjugates （BFNB-OVA）. Purified monoclonal antibody （McAb） was obtained from fluids of ascites, deposited by octanoic acid and ammonium sulfate. The affinity and the specificity of McAb were characterized by ELISA or indirect competitive ELISA. A hybridoma cell line （5D3） secreting anti-carbofuran McAb had been established. The titer of culture medium and ascites was up to 1：2.048 × 10^3 and 1：1.024 × 10^6, respectively, and the subtype of the McAb was IgG1. The affinity constant of the McAb was about 2.54 × 10×9 L mol^-1, with an IC50 value of 1.18 ng mL^-1 and a detection limit of 0.01 ng mL^-1. Cross-reactivity studies showed that the McAb was quiet specific for carbofuran, as among the four analogous compounds, they were all hardly recognized （4.59 × 10^-4% for 2,3-dihydro-2,2- dimethyl-7-benzofuranol and less than 3.0 × 10^4% for others）. The prepared McAb had a very high affinity and specificity, and it could be used to develop ELISA for rapid determination of carbofuran.

Distributed permutation flowshop group scheduling problem(DPFGSP) is studied in this paper. This problem can be regarded as a combination of the distributed flowshop scheduling and group scheduling. An improved iterated local search(dILS)algorithm is proposed to minimize the total flowtime. First of all, we use a simple heuristic algorithm based on the famous NEH heuristics to generate an initial solution. Next, we use the solutions obtained from two different neighborhoods to perform an iterated local search. The acceptance criterion is the simulated-annealing type with a constant temperature. Finally, the proposed dILS algorithm is compared with the existing VND algorithm based on the 810 benchmark instances. The experimental results show that the proposed dILS algorithm has significant advantages in solving the DPFGSP under consideration.
